/* Dark mode is solid black, no colour blobs (branding decision, 2026-07-23 — not a
   bug: the `weather-cat-*` mechanism that tints these blobs by flight category, incl.
   VFR green, was only just fixed to actually apply, then deliberately hidden again for
   dark mode here). The class/watcher stays wired in 01-tokens.css/app.js for light
   theme, which uses its own flat, low-opacity blob palette independent of weather-cat.
