/* VQC 2027 — CAV 2027 palette and type, brutalist treatment: solid colour blocks,
   square corners, no borders, no shadows, no gradients. Orange is an accent only
   (thin rules, small icons, link underlines); large fills are deep blue / teal / grey.
   (conferences.i-cav.org/2027): Public Sans for UI/headings, Source Serif 4
   for prose, a deep-blue brand with a warm orange accent, card surfaces with
   soft shadows and 4px accent edges. */
