feat(a11y): app-wide "Interface size" setting (Accessibility) (#664)

* feat(a11y): app-wide "Interface size" setting (Accessibility)

Adds a dedicated Accessibility -> Interface size control so users on large,
low-DPI displays can enlarge the app's menus, buttons and text (reported: eye
strain on a 32" 1440p panel with no OS scaling).

Mechanism: a host-owned scale capability (window.feedBack.scale) applies a
RELATIVE root font-size (a % of the user-agent base, never a px literal, so a
raised browser/OS base font is respected) and publishes an always-present
--fb-scale token. The rem-based v3 chrome scales together; the gameplay highway
canvas (device-pixel sized) is deliberately untouched, so playback resolution
and FPS are unchanged. Medium (100%) clears the override, so default rendering
is byte-identical to before -- zero blast radius.

- Settings -> new Accessibility tab: Small/Medium/Large/Extra-Large presets
  (0.90/1.00/1.15/1.30) + a fine-tune slider (to 150%).
- Applied pre-paint from an inline <head> script (mirrors the ss-follower
  pattern) so there is no flash-of-reflow on load.
- window.feedBack.scale read-API (get/set + scale:changed, fires once on load)
  so canvas/WebGL surfaces that cannot inherit rem can follow the size. Shape
  mirrors the working-tuning read-API; persists as a durable preference.
- Cosmetic px->rem sweep so text scales cleanly at the larger stops (2 v3.css
  font-sizes + 20 text-[Npx] utilities across 8 v3 files; tailwind.min.css
  rebuilt byte-stable via the pinned toolchain).
- One-time first-run nudge for the large/low-DPI display profile that deep-links
  to the control (never fires once the setting is touched, or on other displays).

v3-only. Verified headless: core apply/persist/reset/reload/UI-sync + nudge
gating, with no console errors.

* fix(v3): regenerate tailwind.min.css to satisfy tailwind-fresh CI (PR #664 review)

Regenerate static/tailwind.min.css via scripts/build-tailwind.sh
(tailwindcss@3.4.19) so a fresh build matches the committed artifact and
the tailwind-fresh CI job's `git diff --quiet` passes. Two consecutive
regenerations are byte-identical.

Also (Fix 2) switch the fine-tune interface-size slider to the documented
transient-preview path: oninput now calls scale.set(v, { persist:false })
so dragging previews without writing localStorage/emitting a commit each
tick, and a new onchange commits with persistence on release.
