/* =========================================================================
   AI House-Design — Examples gallery
   Extends the dashboard drafting aesthetic; all design tokens (paper/ink
   palette, Space Grotesk / IBM Plex type, ink-blue accent, radii, shadows)
   come from styles.css, which is loaded first. This file adds only the
   gallery-specific pieces: intro provenance, example cards, plan frames,
   status footer, caveat notes.
