Replace hardcoded rgba(15, 23, 42, ...) backgrounds and #b31217/#ff7b7b
colors with color-mix() using CSS custom properties (--card-bg, --bg,
--text, --accent-red). This ensures RDS overlays, decoder bar overlays
(APRS, AIS, VDES, FT8, CW), header-main, and tab containers all
respect the selected color scheme and light/dark theme.

CSS: reduce backdrop-filter to modals only, add contain/content-visibility
for inactive tabs, optimize transitions to background-color, pre-compute
color-mix results, add container queries, split themes to lazy-loaded file.
JS: cache DOM refs in render path, add field-level diffing for SSE updates,
replace innerHTML with replaceChildren() in hot paths, add WebGL colour
cache invalidation on theme switch.
HTML: add defer to scripts, lazy-load plugin scripts on tab activation,
SVG sprite sheet for tab icons, template elements for deferred tab content,
improve aria-live/keyboard nav/colour contrast accessibility.
Server: upgrade Cache-Control to immutable, add Brotli compression alongside
gzip with Accept-Encoding negotiation.
Implements all items from docs/frontend_improvements.md except app.js ES
module split (P1, requires major refactor) and Web Worker migration (P3).

The band plan strip was visually positioned between the waterfall and

overview/waterfall) so it renders above the waterfall. Remove the
bp-webgl transparent overrides since the strip now shows colored

bookmark, min elevation, priority)
- Preset dropdown for common weather satellites (NOAA 15/18/19,
Meteor-M2 3/4) that auto-fills name and NORAD ID
- Bookmark selector for each satellite (sets freq, mode, decoders)
