Structural cleanup based on thermo-nuclear code quality review:
- Extract shared color-picker.css and color-popover.css from badges.css (611→85 lines)
- Extract shared lib/presets.js for preset CRUD used by popup and popover
- Unify dark mode to single applyDarkModeClass on <html>, removing 4 scattered functions
- Fix stale closure in startPostObserver, data-driven reload key check
- Remove dead exports, getHelpers wrapper, duplicated colorToHex
- Replace DOM expando properties with state array in popup.js
Net: -318 lines of duplication, no file over 401 lines.

- Default subreddit badge background from transparent to opaque fill
(light: #fde8e0, dark: #3d2518) so page highlights don't bleed through
- Remove lingering "to" text node from tagline when subreddit is hidden
- Hide the <li> wrapping the comments link (not just the <a>) to
eliminate leftover whitespace in the flat-list
- Simplify popup: subreddit bg fields are now color pickers (no longer
need transparent text-input workaround)
