fix: add section colors to THEME_CSS_MAP, trailing bytes label, and missing tests

- Add section color CSS variables to THEME_CSS_MAP in customize.js
- Add AppData catch-all label for trailing bytes when hasName flag is not set
- Add test: ADVERT with payload < 100 bytes (generic Payload branch)
- Add test: ADVERT with combined location + name flags
- Add test: trailing bytes without name flag get AppData label

-# CoreScope v3.4 Release Notes
-
-**The neighbor affinity release.** CoreScope now understands how nodes relate to each other — not just that they exist, but how strongly they're connected. This powers smarter hop resolution, richer node detail pages, and a new graph visualization in analytics.
-
----
-
-## 🎯 Features
-
-### Neighbor Affinity System (7 milestones)
-A complete neighbor relationship engine, from backend graph building to frontend visualization:
-
-- **Affinity graph builder** — computes neighbor relationships and connection strength from packet traffic (#507)
-- **Affinity API endpoints** — REST endpoints to query neighbor data (#508)
-- **Show Neighbors via affinity API** — the existing Show Neighbors feature now uses real affinity data instead of raw packet heuristics (#512, fixes #484)
-- **Affinity-aware hop resolution** — hop resolver uses neighbor affinity to pick better paths (#511)
-- **Node detail neighbors section** — dedicated neighbors panel on the node detail page (#510)
-- **Affinity debugging tools** — inspect and troubleshoot affinity calculations (#521)
-- **Neighbor graph visualization** — interactive neighbor graph in the analytics tab (#513)
-
-### Customizer v2
-- Event-driven state management replaces the old imperative approach — cleaner, more predictable theme/config updates (#503)
-
----
-
-## 🐛 Bug Fixes
-
-- **Stale parsed cache on observation packets** — observation packets now correctly invalidate the JSON parse cache (#505)
-- **Null-guard rAF callbacks** — live page no longer crashes when `requestAnimationFrame` callbacks fire after cleanup (#506)
-- **Customizer v2 phantom overrides** — fixed phantom config entries, missing defaults, and stale dark mode state (#520)
-- **Neighbor affinity empty results** — fixed pubKey field name mismatch causing empty affinity graphs (#524)
-- **Home defaults in server theme** — server-side theme config now includes home page defaults (#526)
-- **Neighbor UI crash + dark mode** — fixed Show Neighbors crash and improved dark mode contrast (#527)
-- **Home page steps + FAQ** — both steps AND FAQ now render correctly on the home page (#529)
-
----
-
-## ⚡ Performance
-
-- **Cached JSON.parse for packet data** — packet payloads are parsed once and cached, avoiding redundant `JSON.parse` calls on repeated access (#400)
-
----
-
-## Known Limitations
-
-- **Affinity graph scales with traffic volume** — networks with very low packet rates may show weak or missing neighbor relationships until enough data accumulates
-- **Debugging tools are developer-facing** — the affinity debug panel (#521) is functional but not polished for end-user consumption
-- **Customizer v2 migration** — custom themes saved under v1 may need to be re-applied after upgrade

-# Customizer Rework Spec
-
-## Overview
-
-The current customizer (`public/customize.js`) suffers from fundamental state management issues documented in [issue #284](https://github.com/Kpa-clawbot/CoreScope/issues/284). State is scattered across 7 localStorage keys, CSS updates bypass the data layer, and there's no single source of truth for the effective configuration.
-
-This spec defines a clean rework based on event-driven state management with a single data flow path. The goal: predictable state, minimal storage footprint, portable config format, and zero ambiguity about which values are active and why.
-
-## Design Decisions
-
-These are agreed and final. Do not reinterpret or deviate.
-
-1. **Three state layers:** server defaults (immutable after fetch), user overrides (delta in localStorage), effective config (computed via merge, never stored directly).
-2. **Single data flow:** user action → debounce (~300ms) → write delta to localStorage → read back from localStorage → merge with server defaults → apply CSS variables. No shortcuts, no optimistic CSS updates (see Decision #12 for the one exception).
-3. **One localStorage key:** `cs-theme-overrides` — replaces the current 7 scattered keys (`meshcore-user-theme`, `meshcore-timestamp-mode`, `meshcore-timestamp-timezone`, `meshcore-timestamp-format`, `meshcore-timestamp-custom-format`, `meshcore-heatmap-opacity`, `meshcore-live-heatmap-opacity`).
-4. **Universal format:** same shape as the server's `ThemeResponse` plus additional keys. Works identically for user export, admin `theme.json`, and user import.
-5. **User overrides always win** in merge — `merge(serverDefaults, userOverrides)` = effective config.
-6. **Override indicator:** shown in customizer panel ONLY when override value differs from current server default.
-7. **No silent pruning:** overrides stay in localStorage until the user explicitly resets them (per-field reset or full reset). The delta may contain values that happen to match current server defaults — that's fine. User intent is preserved; nothing silently disappears.
-8. **Per-field reset:** remove a single key from the delta → re-merge → re-apply CSS.
-9. **Full reset:** `localStorage.removeItem('cs-theme-overrides')` → re-merge (effective = server defaults) → re-apply CSS.
-10. **Export = dump delta object as JSON download. Import = validate shape, write to localStorage, trigger re-merge.**
-11. **No CSS magic:** CSS variables ONLY update after the localStorage round-trip completes. No optimistic updates (see Decision #12 for the one exception).
-12. **Color picker optimistic CSS exception:** For continuous inputs (color pickers, sliders), CSS is updated optimistically during `input` events for visual responsiveness. The localStorage write only happens on `change` event (mouseup/blur). On `change`, the full pipeline runs: write → read → merge → apply (which will match the optimistic state). If the user refreshes mid-drag before `change` fires, the change is lost — this is acceptable. This is the ONLY exception to the localStorage-first rule.
-
-## Dark/Light Mode
-
-The customizer treats light and dark mode as separate override sections:
-
-- **`theme`** stores light mode color overrides.
-- **`themeDark`** stores dark mode color overrides.
-- When the user changes a color in the customizer, it writes to whichever section matches their current mode: `theme` if light, `themeDark` if dark.
-- The dark/light mode toggle preference (`meshcore-theme` localStorage key) is **separate** from the delta object. It is a view preference, not a customization — it is not stored in `cs-theme-overrides`.
-- The customizer UI shows color fields for the currently active mode only. Switching modes re-renders the color fields with values from the matching section.
-
-## Presets
-
-The existing preset themes are preserved and flow through the standard pipeline:
-
-**Available presets:** Default, Ocean, Forest, Sunset, Monochrome.
-
-**How presets work:**
-- Clicking a preset writes its values to localStorage via the same pipeline as any other change: preset data → `writeOverrides()` → read back → merge → apply CSS.
-- Presets are NOT special — they are pre-built delta objects applied through the standard flow.
-- Each preset contains both `theme` (light) and `themeDark` (dark) sections, plus any other overrides the preset defines (e.g., `nodeColors`).
-- **"Reset to Default"** = clear all overrides (equivalent to full reset: `localStorage.removeItem('cs-theme-overrides')` → re-merge → apply).
-
-**Preset data format:** Same shape as the delta object. Example:
-
-```json
-{
-  "theme": {
-    "accent": "#0077b6",
-    "navBg": "#03045e",
-    "background": "#f0f7fa"
-  },
-  "themeDark": {
-    "accent": "#48cae4",
-    "navBg": "#03045e",
-    "background": "#0a1929"
-  }
-}
-```
-
-Applying a preset **replaces** the entire delta (it's a `writeOverrides(presetData)`, not a merge onto existing overrides). The user can then further customize individual fields on top.
-
-## Data Model
-
-### Delta Object Format
-
-The user override delta is a sparse object — it only contains fields the user has explicitly changed. The shape mirrors the server's `ThemeResponse` (from `/api/config/theme`) plus additional client-only sections:
-
-```json
-{
-  "branding": {
-    "siteName": "string — site name override",
-    "tagline": "string — tagline override",
-    "logoUrl": "string — custom logo URL",
-    "faviconUrl": "string — custom favicon URL"
-  },
-  "theme": {
-    "accent": "string — CSS color, light mode accent",
-    "accentHover": "string — CSS color, light mode accent hover",
-    "navBg": "string — CSS color, nav background",
-    "navBg2": "string — CSS color, nav secondary background",
-    "navText": "string — CSS color, nav text",
-    "navTextMuted": "string — CSS color, nav muted text",
-    "background": "string — CSS color, page background",
-    "text": "string — CSS color, body text",
-    "textMuted": "string — CSS color, muted text",
-    "border": "string — CSS color, borders",
-    "surface1": "string — CSS color, surface level 1",
-    "surface2": "string — CSS color, surface level 2",
-    "cardBg": "string — CSS color, card backgrounds",
-    "contentBg": "string — CSS color, content area background",
-    "detailBg": "string — CSS color, detail pane background",
-    "inputBg": "string — CSS color, input backgrounds",
-    "rowStripe": "string — CSS color, alternating row stripe",
-    "rowHover": "string — CSS color, row hover highlight",
-    "selectedBg": "string — CSS color, selected row background",
-    "statusGreen": "string — CSS color, healthy status",
-    "statusYellow": "string — CSS color, degraded status",
-    "statusRed": "string — CSS color, critical status",
-    "font": "string — CSS font-family for body text",
-    "mono": "string — CSS font-family for monospace"
-  },
-  "themeDark": {
-    "/* same keys as theme — dark mode overrides */"
-  },
-  "nodeColors": {
-    "repeater": "string — CSS color",
-    "companion": "string — CSS color",
-    "room": "string — CSS color",
-    "sensor": "string — CSS color",
-    "observer": "string — CSS color"
-  },
-  "typeColors": {
-    "ADVERT": "string — CSS color",
-    "GRP_TXT": "string — CSS color",
-    "TXT_MSG": "string — CSS color",
-    "ACK": "string — CSS color",
-    "REQUEST": "string — CSS color",
-    "RESPONSE": "string — CSS color",
-    "TRACE": "string — CSS color",
-    "PATH": "string — CSS color",
-    "ANON_REQ": "string — CSS color"
-  },
-  "home": {
-    "heroTitle": "string",
-    "heroSubtitle": "string",
-    "steps": "[array of {emoji, title, description}]",
-    "checklist": "[array of strings]",
-    "footerLinks": "[array of {label, url}]"
-  },
-  "timestamps": {
-    "defaultMode": "string — 'ago' | 'absolute'",
-    "timezone": "string — 'local' | 'utc'",
-    "formatPreset": "string — 'iso' | 'iso-seconds' | 'locale'",
-    "customFormat": "string — custom strftime-style format"
-  },
-  "heatmapOpacity": "number — 0.0 to 1.0",
-  "liveHeatmapOpacity": "number — 0.0 to 1.0"
-}
-```
-
-**Rules:**
-- All sections and keys are optional. An empty object `{}` means "no overrides."
-- The `timestamps`, `heatmapOpacity`, and `liveHeatmapOpacity` keys are client-only extensions — not part of the server's `ThemeResponse`, but included in the universal format for portability.
-
-### localStorage Key
-
-**Key:** `cs-theme-overrides`
-**Value:** JSON string of the delta object above.
-**Absent key** = no overrides = effective config equals server defaults.
-
-### Dark/Light Mode Preference
-
-**Key:** `meshcore-theme`
-**Value:** `"dark"` or `"light"` (or absent = follow system preference).
-**This key is NOT part of the delta object.** It controls which mode is active, not which colors are used. The delta stores overrides for both modes independently in `theme` and `themeDark`.

-## Function Signatures
-
-### `readOverrides() → object`
-
-Reads `cs-theme-overrides` from localStorage, parses as JSON. Returns empty object `{}` on missing key, parse error, or non-object value. Never throws.
-
-### `writeOverrides(delta: object) → void`
-
-Serializes `delta` to JSON and writes to `cs-theme-overrides` in localStorage. If `delta` is empty (`{}`), removes the key entirely.
-
-**Validation on write:**
-- Color values must match: `#hex` (3, 4, 6, or 8 digit), `rgb()`, `rgba()`, `hsl()`, `hsla()`, or CSS named colors. Invalid color values are rejected (not written) with `console.warn`.
-- Numeric values (`heatmapOpacity`, `liveHeatmapOpacity`) must be finite numbers in the range 0–1. Invalid values are rejected with `console.warn`.
-- Timestamp enum values are validated against known options (`defaultMode`: `'ago'`/`'absolute'`; `timezone`: `'local'`/`'utc'`; `formatPreset`: `'iso'`/`'iso-seconds'`/`'locale'`). Invalid values are rejected with `console.warn`.
-
-**Quota error handling:**
-- Wrap `localStorage.setItem` in try/catch.
-- On `QuotaExceededError`: show a visible warning to the user ("Storage full — changes may not be saved"), log to console.
-- Do NOT silently swallow the error.
-
-### `computeEffective(serverConfig: object, userOverrides: object) → object`
-
-Deep merges `userOverrides` onto `serverConfig`. For each section (e.g., `theme`, `nodeColors`), if `userOverrides` has the section, its keys override the corresponding `serverConfig` keys. Top-level non-object keys (e.g., `heatmapOpacity`) are directly overridden.
-
-Returns a new object — neither input is mutated.
-
-**Merge rules:**
-- Object sections: shallow merge per section (`Object.assign({}, server.theme, user.theme)`)
-- Array sections (e.g., `home.steps`): full replacement (user array wins entirely, no element-level merge)
-- Scalar sections (e.g., `heatmapOpacity`): direct replacement
-
-After computing the effective config, writes it to `window.SITE_CONFIG` atomically (single assignment, not piecemeal mutations).
-
-### `applyCSS(effectiveConfig: object) → void`
-
-Maps effective config values to CSS custom properties on `:root`. Behavior:
-
-1. Reads the current mode (light/dark) from the `meshcore-theme` localStorage key, falling back to system preference (`prefers-color-scheme`).
-2. Applies the matching section's values: `theme` for light mode, `themeDark` for dark mode.
-3. Also applies mode-independent values: node colors as `--node-{role}`, type colors as `--type-{name}`, font families as `--font-body` and `--font-mono`.
-4. Does NOT generate dual CSS rule blocks — only the current mode's values are applied to `:root`.
-5. On dark/light mode toggle, `applyCSS` is called again to re-apply the correct section.
-
-Updates the `<style>` element (create if absent, reuse if present). Dispatches a `theme-changed` CustomEvent on `window` after applying.
-
-### `theme-changed` Event
-
-- `theme-changed` is a bare `CustomEvent` with no payload (matches current behavior).
-- After each merge cycle, the effective config is written to `window.SITE_CONFIG` atomically (single assignment).
-- `window.SITE_CONFIG` is the canonical readable source for effective config throughout the app. All existing listeners that read from `SITE_CONFIG` continue to work without changes.
-
-### `setOverride(section: string, key: string, value: any) → void`
-
-Sets a single override. For nested sections (e.g., `section='theme'`, `key='accent'`), sets `delta[section][key] = value`. For top-level scalars (e.g., `section=null`, `key='heatmapOpacity'`), sets `delta[key] = value`.
-
-Follows the full data flow: read → update → write → read-back → merge → apply CSS → dispatch `theme-changed`. Debounced at ~300ms (the debounce wraps the write-through-to-CSS portion).
-
-### `clearOverride(section: string, key: string) → void`
-
-Removes a single key from the delta. If the section becomes empty after removal, removes the section too. Triggers the full data flow (no debounce — resets should feel instant).
-
-### `migrateOldKeys() → object | null`
-
-One-time migration. Checks for any of the 7 legacy localStorage keys. If found:
-1. Reads all legacy values
-2. Maps them into the new delta format (see Migration Plan)
-3. Writes the merged delta to `cs-theme-overrides`
-4. Removes all 7 legacy keys
-5. Returns the migrated delta
-
-Returns `null` if no legacy keys found.
-
-### `validateShape(obj: any) → { valid: boolean, errors: string[] }`
-
-Validates that an imported object conforms to the expected shape:
-- Must be a plain object
-- Top-level keys must be from the known set: `branding`, `theme`, `themeDark`, `nodeColors`, `typeColors`, `home`, `timestamps`, `heatmapOpacity`, `liveHeatmapOpacity`
-- Section values must be objects (where expected) or correct scalar types
-- Color values are validated: must match `#hex` (3, 4, 6, or 8 digit), `rgb()`, `rgba()`, `hsl()`, `hsla()`, or CSS named colors
-- Numeric values (`heatmapOpacity`, `liveHeatmapOpacity`) must be finite numbers in range 0–1
-- Timestamp enum values validated against known options
-
-Unknown top-level keys cause a warning but don't fail validation (forward compatibility).
-
-## Migration Plan
-
-On first page load, before the normal init flow:
-
-1. Check if `cs-theme-overrides` already exists → if yes, skip migration.
-2. Check if ANY of the 7 legacy keys exist in localStorage.
-3. If legacy keys found, build a delta object using the exact mapping below:
-
-### Field-by-Field Migration Mapping
-
-```
-meshcore-user-theme (JSON) → parse, map directly:
-  .branding  → delta.branding
-  .theme     → delta.theme
-  .themeDark → delta.themeDark
-  .nodeColors → delta.nodeColors
-  .typeColors → delta.typeColors
-  .home      → delta.home
-  (any other keys are dropped)
-
-meshcore-timestamp-mode           → delta.timestamps.defaultMode
-meshcore-timestamp-timezone       → delta.timestamps.timezone
-meshcore-timestamp-format         → delta.timestamps.formatPreset
-meshcore-timestamp-custom-format  → delta.timestamps.customFormat
-meshcore-heatmap-opacity          → delta.heatmapOpacity (parseFloat)
-meshcore-live-heatmap-opacity     → delta.liveHeatmapOpacity (parseFloat)
-```
-
-4. Write the assembled delta to `cs-theme-overrides`.
-5. Delete all 7 legacy keys.
-6. Continue with normal init.
-
-**Edge cases:**
-- If `meshcore-user-theme` contains invalid JSON, skip it (log a warning to console).
-- If a legacy value is empty string or null, skip that field.
-- Migration runs exactly once — the presence of `cs-theme-overrides` (even as `{}`) prevents re-migration.
-
-## `allowCustomFormat` — User Preferences Trump
-
-The server-side `allowCustomFormat` gate is not enforced client-side. If a user imports a delta with a custom format, it's applied regardless. The server controls what formats are available in the UI (whether the custom format input field is shown), but does not block stored preferences.
-
-## Override Indicator UX
-
-In the customizer panel, each field that has an active override (value differs from server default) shows a visual indicator:
-
-- **Indicator:** A small dot or icon (e.g., `●` or a reset arrow `↺`) adjacent to the field label.
-- **Color:** Use the accent color to draw attention without being noisy.
-- **Behavior:** Clicking the indicator resets that single field (calls `clearOverride`).
-- **Tooltip:** "Reset to server default" or "This value differs from the server default."
-- **Absence:** Fields matching the server default show no indicator — clean and minimal.
-
-**Section-level indicator:** If any field in a section (e.g., "Theme Colors") is overridden, the tab/section header shows a count badge (e.g., "Theme Colors (3)").
-
-**"Reset All" button:** Always visible at bottom of panel. Confirms before executing (`localStorage.removeItem` + re-merge).
-
-## UX Requirements
-
-### Browser-Local Banner
-
-The customizer panel must display a persistent, always-visible notice:
-
-> **"These settings are saved in your browser only and don't affect other users."**
-
-This is NOT a tooltip, NOT a dismissible popup — it must be always visible in the panel header or footer area. Users must understand at a glance that their changes are local.
-
-### Auto-Save Indicator
-
-Show a persistent status in the customizer panel footer, Google Docs style — subtle but always present:
-
-- **Default state:** "All changes saved" (muted text)
-- **During debounce:** "Saving..." (muted text)
-- **On quota error:** "⚠️ Storage full — changes may not be saved" (red text, persistent until resolved)
-
-The indicator reflects the actual state of the localStorage write, not just the UI action.
-
-## Server Compatibility
-
-The delta format is intentionally shaped to be a valid subset of the server's `theme.json` admin config file. This means:
-
-- **User export → admin import:** An admin can take a user's exported JSON and drop it into `theme.json` as server defaults. The `timestamps`, `heatmapOpacity`, and `liveHeatmapOpacity` keys are ignored by the current server (it doesn't read them from `theme.json`), but they don't cause errors.
-- **Admin config → user import:** A `theme.json` file can be imported as user overrides. Unknown server-only keys are ignored by the client.
-- **Round-trip safe:** Export → import produces identical delta (assuming no server default changes between operations).
-
-The server's `ThemeResponse` struct currently returns: `branding`, `theme`, `themeDark`, `nodeColors`, `typeColors`, `home`. The client-only extensions (`timestamps`, `heatmapOpacity`, `liveHeatmapOpacity`) are additive — they extend the format without conflicting.
-
-## Testing Requirements
-
-### Unit Tests (Node.js, no browser required)
-
-1. **`readOverrides`**
-   - Returns `{}` when key is absent
-   - Returns `{}` when key contains invalid JSON
-   - Returns `{}` when key contains a non-object (string, array, number)
-   - Returns parsed object when key contains valid JSON object
-
-2. **`writeOverrides`**
-   - Writes serialized JSON to localStorage
-   - Removes key when delta is empty `{}`
-   - Round-trips correctly (write → read = identical object)
-   - Rejects invalid color values with console.warn
-   - Rejects out-of-range numeric values with console.warn
-   - Rejects invalid timestamp enum values with console.warn
-   - Handles QuotaExceededError gracefully (warns user, does not throw)
-
-3. **`computeEffective`**
-   - Returns server defaults when overrides is `{}`
-   - Overrides a single key in a section
-   - Overrides multiple keys across sections
-   - Does not mutate either input
-   - Handles missing sections in overrides gracefully
-   - Array values (e.g., `home.steps`) are fully replaced, not merged
-   - Top-level scalars (`heatmapOpacity`) are directly replaced
-
-4. **`setOverride` / `clearOverride`**
-   - Setting a value stores it in the delta
-   - Clearing a key removes it from delta
-   - Clearing the last key in a section removes the section
-   - Full data flow executes (CSS vars updated)
-
-5. **`migrateOldKeys`**
-   - Migrates all 7 keys correctly using exact field mapping
-   - Handles partial migration (only some keys present)
-   - Handles invalid JSON in `meshcore-user-theme`
-   - Removes all legacy keys after migration
-   - Skips migration if `cs-theme-overrides` already exists
-   - Returns null when no legacy keys found
-   - Drops unknown keys from `meshcore-user-theme`
-
-6. **`validateShape`**
-   - Accepts valid delta objects
-   - Accepts empty object
-   - Rejects non-objects (string, array, null)
-   - Warns on unknown top-level keys (doesn't reject)
-   - Validates section types (object vs scalar)
-   - Rejects invalid color values
-   - Rejects out-of-range opacity values
-   - Rejects invalid timestamp enum values
-
-### Browser/E2E Tests (Playwright)
-
-1. **Customizer opens and shows current values** — fields reflect effective config.
-2. **Changing a color updates CSS variable** — after debounce, `:root` has new value.
-3. **Override indicator appears** when value differs from server default.
-4. **Per-field reset** removes override, reverts to server default, indicator disappears.
-5. **Full reset** clears all overrides, all fields show server defaults.
-6. **Export** downloads a JSON file with current delta.
-7. **Import** applies overrides from uploaded JSON file.
-8. **Migration** — set legacy keys, reload, verify they're migrated and removed.
-9. **Preset application** — clicking a preset applies its colors, fields update.
-10. **Dark/light mode toggle** — switching mode re-applies correct section's CSS vars.
-11. **Browser-local banner** — verify persistent notice is visible in customizer panel.
-12. **Auto-save indicator** — verify status text updates during and after changes.
-
-## What's NOT In Scope
-
-- **Undo/redo stack** — could be added as P2. For v1, per-field reset to server default is the only revert mechanism.
-- **Cross-tab synchronization** — two tabs editing simultaneously may clobber each other's changes. Acceptable for v1.
-- **Server-side timestamp config** (`allowCustomFormat` gate) — remains server-only, not exposed in the customizer delta. The server controls UI availability but does not block stored preferences (see `allowCustomFormat` section above).
-- **Admin import endpoint** — no server API for uploading `theme.json` via the UI. Admins edit the file directly. Future work.
-- **Map config overrides** (`mapDefaults.center`, `mapDefaults.zoom`) — separate concern, not part of theme. Future work.
-- **Geo-filter config** — server-only. Not in scope.
-- **Per-page layout preferences** (column widths, sort orders) — separate from theming. Future work.
