/* ============================================================
   THEME SCHEMA
   Every theme file defines all of these tokens, once for light
   and once for dark (the dark block is repeated for the explicit
   html[data-theme="dark"] case and the system-preference case).
   Layout CSS in styles.css only ever reads these.

   Surfaces   --paper (page)  --surface (panels)  --surface-2  --line (hairlines)  --hero-bg
   Text       --ink  --muted
   Accent     --accent (controls)  --accent-ink (links on paper)  --accent-soft (tint)  --focus
   Buttons    --cta-bg  --cta-ink
   Type       --font-display  --font-body  --display-weight  --display-tracking
   Shape      --radius (images, inputs)  --radius-lg (panels)
   Depth      --phone-shadow
   Rhythm     --section (vertical space between sections)

/* Theme: Indigo. Cool lavender-grey paper, deep indigo ink, the app's lavender as the accent;
