- Delete orphaned CSS files (color-theme.css, logo-toggle.css,
skeleton.css, main.new.css) - replaced by modular equivalents
- Delete 08-contexts/_print.css - wrongly created during modularization
- Remove 08-contexts folder (now empty)
- Add print.css as standalone with media="print" in HTML
- Update stale comments referencing old file names
- Remove _print.css import from main.css
print.css remains standalone and will NOT be bundled, as it's a
special case loaded only when printing (media="print").
Light theme:
- Change background from #b8bbbe to #d6d6d6 (light gray)
- Add concentric squares pattern with 4 gradient layers
- Creates subtle geometric texture on gray background
Dark theme:
- Change background from rgb(82, 86, 89) to #3a3a3a (medium gray)
- Add diagonal grid pattern with green glow (rgba(0, 255, 128, 0.15))
- 45deg and -45deg crosshatch creates retro tech aesthetic
Both patterns use CSS custom properties (--page-bg-pattern) and are
applied via background-image in _reset.css. Patterns are fixed and
maintain visibility across theme switches.
