/* Read Them Well — web tokens & base styles (v2, chocolate edition)
   Companion to rtw-brand-spec.md. Reference design: RTW Homepage - App Vibe.dc.html

   Rules this file encodes:
   - Sections are full-bleed color fields. No page-wide container, no card-on-card.
   - Elevation is rare: max two floating callouts per page, each straddling a color seam.
   - Rounded UI (cards/tiles/inputs/pills). Book covers stay square.
   - Flat fills; the only gradient is the 50/50 seam behind a floating callout.
   - Shadows are chocolate-tinted, never gray. Buttons and inputs never carry shadow. */
