## Summary
Fixes#1060 — free-win CSS pass for touch usability.
- All major interactive controls (`.btn`, `.btn-icon`, `.nav-btn`,
`.nav-link`, `.ch-icon-btn`, `.ch-remove-btn`, `.ch-share-btn`,
`.ch-gear-btn`, `.panel-close-btn`, `.mc-jump-btn`, `button.ch-item`)
now declare `min-height: 48px` / `min-width: 48px`. Hit-area grows;
visual padding/icon size unchanged on desktop because the rules use
`inline-flex` centering.
- Added visible `:active` feedback (background shift + `transform:
scale(0.92–0.97)` + opacity) on every button class — touch devices have
no hover, so `:active` is the only press signal.
- Hover-only `.sort-help` tooltip rule is now wrapped in `@media (hover:
hover)`; added a CSS-only `:focus` / `:focus-within` tap-to-reveal path
with a visible focus ring so the same content is reachable on touch (and
via keyboard).
- All changes scoped to the `=== Touch Targets ===` section. No other
CSS section modified, no JS touched, no markup edits.
## Acceptance criteria
- [x] All interactive controls reach 48×48 CSS-px touch target (verified
by `test-touch-targets.js`).
- [x] Every button has a visible `:active` state (no hover-only
feedback).
- [x] Hover tooltip rule is gated behind `@media (hover: hover)`, with
`:focus-within` tap-to-reveal fallback.
- [x] Desktop visuals preserved (padding-based, not visual-size-based).
## TDD
- Red commit `327473b` — `test-touch-targets.js` asserts every required
selector/property; it compiles and fails on assertion against pre-change
CSS.
- Green commit `e319a8f` — Touch Targets section rewrite; test passes.
