   reading.css — the "Plan reading" card (js/reading-report.js)
   lane cc-impl-1 F1 · 2026-10-10 · NEW FILE. css/styles.css is FROZEN, so this is
   a separate sheet and MUST load AFTER it. Every rule is prefixed .rdg- and
   every colour is a design token, so both themes work: `:root` is the DARK
   palette and `:root.light` (a CLASS on <html>) overrides it.

   Two things this file deliberately does NOT do:
   . borrow the report's badge classes (.qa-count is a SOLID TEAL interactive
     pill — `--blue` is teal). Labels here are outlined tags, never solid pills,
     so a label cannot be mistaken for a button.
   . use a fixed grey. The only literal colours are translucent tints of the
     accent tokens' own values, which read on either background.
   ═══════════════════════════════════════════════════════════════════════════ */

/* Two line weights, both from the theme-aware grey scale. `--border-color` is a
   60%-alpha #2e2e2e in the dark theme: over a #242424 chip it does not read as
   an edge at all, so outlined tags and chips use the next step up. */
