feat(css): fluid scaffolding — clamp() spacing/type/container tokens (#1054) (#1066)

## Summary

Lands the **fluid CSS foundation** for the responsive scaffolding effort
(parent #1050). Pure additive change to the top of `public/style.css` —
no component CSS touched.

## What changed

### New tokens in `:root`
- **Spacing scale** — `--space-xs … --space-2xl` via `clamp()`. 1440px
targets match the prior hardcoded `4 / 8 / 16 / 24 / 32 / 48` px values
to within ~1px.
- **Type scale** — `--fs-sm … --fs-2xl` via `clamp(min, vw-based, max)`.
Floors keep text readable at 768px; caps prevent runaway growth at
2560px+.
- **Radii** — `--radius-sm/md/lg` via `clamp()`.
- **Container layout** — `--gutter` (`clamp()`) and `--content-max`
(`min(100% - 2*gutter, 1600px)`) for fluid horizontal layout without
media queries.

### Base consumption
- `html, body` now sets `font-size: var(--fs-md)`.

### Parallel-work safety
- Added `FLUID SCAFFOLDING` section header at the top.
- Added `COMPONENT STYLES` section header marking where the rest of the
file (nav, tables, charts, map, packets, analytics …) begins. Sibling
tasks 1050-3..6 / 1052-* edit inside that region and won't conflict with
this PR.

## TDD

- **Red:** `2d6f90a` — `test-fluid-scaffolding.js` asserts the new
tokens exist with `clamp()`/`min()`, that `html, body` consumes
`--fs-md`, and that the section marker is present. Fails on assertions
(15 failed, 0 passed).
- **Green:** `7b4d59b` — implementation in `public/style.css`. All 15
assertions pass.

## Acceptance criteria

- [x] Fluid spacing scale `--space-xs..--space-2xl` via `clamp()`
- [x] Fluid type scale `--fs-sm..--fs-2xl` via `clamp()`
- [x] Replace base body font-size with the new token
- [x] Container layout vars `--content-max`, `--gutter` via
`min()`/`clamp()`
- [x] No component CSS edits (only `:root`, `html`, `body`)
- [x] No visual regression at 1440px (token targets numerically match
prior px values)

## Notes for reviewers

- Pre-existing `test-frontend-helpers.js` failure on master is unrelated
(`nodesContainer.setAttribute is not a function`) and not introduced
here.
- `--content-max` uses `min(100% - 2*gutter, 1600px)` — the `100% - …`
arm wins on small viewports and guarantees a gutter always remains.

Fixes #1054
