/* ==========================================================================
   Le Labo × Formula 1 campaign — "Grid 26" speculative collaboration.
   Loaded only on campaigns/le-labo-f1.html, after the theme-agnostic
   assets/css/style.css (navbar/footer, --maroon/--cream/--gold tokens).
   Scoped under .lelabo-theme (set on <body>). The desktop composition is
   six full-width raster artwork panels (each already final editorial
   design, approved phase by phase) with no CSS-built layout of its own —
   every panel is width:100%/height:auto, so the whole page scales
   proportionally at any viewport with no separate mobile artwork.

   The campaigns-overview entry (.campaign-card-lelabo, bottom of this
   file) is intentionally NOT scoped under .lelabo-theme — it is used on
   marketing-campaigns.html, which carries no theme class.
