/* brand-brain.css — section-specific layout for the Brand Brain panel.
   Consumes notion.css tokens (see public/css/notion.css). All styling under
   the [data-notion-theme="light"] scope inherits Notion design language
   from notion.css; this file only adds Brand Brain layout primitives
   (7-card grid, sticky chrome, status chips, coverage badges).

   Layout plan (selectors):
     .brand-brain-panel              — 2-col grid container (desktop), 1-col ≤ 768px
     .brand-brain-card               — Notion-styled section card
     .brand-brain-card--full         — spans both grid columns (Campaigns row)
     .brand-brain-card__title        — section heading
     .brand-brain-card__body         — content area
     .brand-selector-chrome          — sticky top bar (z-index: 10)
       .brand-selector-chrome__brand
       .brand-selector-chrome__dropdown
       .brand-selector-chrome__refresh
       .brand-selector-chrome__refreshed-at
       .brand-selector-chrome__coverage
     .live-state-chip{.ok,.stale,.unauth,.error}
     .coverage-badge{.core,.legacy,.mixed}

   Section order (matches T15 design spec):
     1. Identity   2. Voice & DNA   3. Personas   4. Differentiation
     5. Strategy   6. Live state    7. Campaigns (full-width row)

   Note on status colors: chip/badge background tints intentionally use
   inline rgba() / status-color literals where notion.css does not expose a
   matching semantic token. Foreground text colors all bind to var(--success),
   var(--warning), var(--danger), var(--info) declared on
   [data-notion-theme="light"] in notion.css.
