/* Gap Hunter Labs -- home (index.html and es/index.html).
   Rewritten 2026-10-18 for the "engineering notebook" redesign. The old
   sheet (2,971 lines, ~40% unused) carried the catalog dashboard, the
   slider and several earlier redesigns; none of it is used by the new
   home. Fonts, colors and radii come from /css/theme.css; header, footer,
   search modal and shared components from /css/shell.css. */
