/* Avid OS, Version C "Bento". Base stylesheet.
   Spec: docs/01_design/BENTO_DIRECTION.md. Brand tokens: docs/01_design/BRAND.md.
   Station styles live in styles/<station>.css and scope themselves with [data-station="<id>"].

   Contract for station builders:
   - #app is a 12-column bento grid. A direct child with span-N takes N columns; anything else spans the row.
   - .bento is the same grid for a nested group. Spans: .span-1 to .span-12. Height: .rows-2 (row unit 140 px).
   - .tile is the only surface. Variants: .tile-mist, .tile-blue (hero only), .tile-ink (one per screen).
   - .tile-label, .tile-title, .big (.is-xl), .big-sub, .tile-action, .btn-primary, .btn-light, .btn-text. */

/* ---------- 1. Tokens ----------
   The Statement values live in styles/tokens.css (ported from design-18). The names below are Version C's own,
   kept so every station stylesheet keeps working, and pointed at the Statement palette. */
