/* Konstellar browser app — same system as the website (ADR 0021 rev. 2) and
   the iOS app (ADR 0022). Loads after /shared.css, which supplies the
   Newsreader + Commissioner @font-face rules.

   - Colour: mineral white canvas, near-black ink, one deep wine accent; cool
     mist only for selected/hover; clean white only for fields and controls.
     Dark mode follows prefers-color-scheme with the ADR 0022 dark values.
   - Type: Newsreader for headlines, key statements, result titles and
     reflection questions; Commissioner for everything else. Reading text
     never below 16px.
   - Form: no cards, no pills, no shadows. Space and 1px rules separate
     sections; 8px radius on controls only.
   - Threads: only on the Muster sources ("Woher das kommt"). Filled node =
     computed, open node + dotted line = needs more data. Drawn once; off
     under prefers-reduced-motion. */
