rmsitzandClaude Sonnet 5 c871d6efae Visual polish: theme-aware colors, collapsible cards, skeletons, hover consistency
Templates only, no backend changes:

- Fixed the real bug: JS-generated status/loading text and a few component
  styles used hardcoded hex (#007acc, #999/#666, #28a745, #ff6b6b) instead
  of the CSS variables the theme system already provides, so they didn't
  track the user's chosen theme/accent - most visible on Light or any named
  theme other than the default. Added --success/--error to all 5 templates'
  :root blocks and replaced every non-:root occurrence. Left the
  .lesson-type badge colors and generic UI chrome grays alone (intentional,
  not theme-dependent). Verified live by switching to Nord and Light themes.
- Dashboard cards (Library Stats, Next Up, Pick Back Up, Recently Added,
  Continue Watching, Recently Viewed) are now collapsible, state remembered
  per device via localStorage - the no-course dashboard had grown to 7
  stacked cards.
- Course page's three action buttons get consistent compact sizing and
  icons instead of a plain stack.
- Library browser and transcript search show shimmering skeleton rows
  instead of bare "Loading..."/"Searching..." text while a fetch is in
  flight.
- Hover treatment made consistent: transcript results get the same lift
  .lesson-item already had, heatmap cells get a GitHub-style hover
  scale-up, and Notes Hub links get a background-chip hover.
