/* BlindSpot report UI. Plain CSS, no framework.

   Concept: "Screen off". The interface is the page as it is heard, not seen.
   - Dark first: the black of a powered-down screen (#0d0d0c), warm off-white text. A light theme follows
     prefers-color-scheme, where black text sits on off-white and yellow becomes a highlighter fill.
   - One accent, the yellow of tactile paving and warning strips (#ffd200). It marks barriers ("blind spots"),
     focus, the live / speaking state and primary actions. Yellow is never used as text on a light background.
   - Type: Atkinson Hyperlegible Next and Atkinson Hyperlegible Mono, designed by the Braille Institute for
     readers with low vision. Headings are set like screen reader announcements: a dim role, then the content.
   - Transcripts and other "heard" panels stay dark in both themes: that is the screen switched off.
   Fonts are self-hosted in fonts/ (SIL Open Font License, see the OFL-*.txt files there).

   Contrast (WCAG 2.x ratios, checked with a script):
   dark  #f2efe6 on #0d0d0c 16.9 · #c4c0b5 10.7 · #9a968b 6.6 (5.8 on #1d1c19) · #ffd200 13.4 · #8fd19e 10.9
         #0d0d0c on #ffd200 13.4 · field / control borders #6a675e 3.4
   light #0d0d0c on #f4f2ec 17.4 · #3a3833 10.5 · #625f57 5.7 (5.1 on #e9e6dd) · #2f6b3f 5.7
         control borders #7d796f 3.9 · yellow only as a fill behind black text (13.4). */
