Perform Daily Design System Audit (2026-01-25)

- Fix Tailwind color violations in `js/ui/components/EmbedPlayerModal.js` by using semantic tokens.
- Add `js/embed.js`, `tests/unit/embed-accent.test.mjs`, and `tests/visual/embed-layout.spec.ts` to `scripts/check-hex.js` allowlist as they have legitimate hex usage (fallback/tests).
- Add `js/embed.js` and `js/ui/components/VideoModal.js` to `scripts/check-inline-styles.mjs` allowlist as they use sanctioned dynamic styles.
- Verified all lint checks pass with `scripts/daily-design-system-audit.mjs`.
