/* University — shared design system: "Blueprint" (Hirst Academy, 2026-09-10).
   The academy as precision instrument: hairline rules, corner-bracket framing, monospace data labels,
   a dot-grid texture on dark panels. Dark-first; light via :root[data-theme="light"].
   Palette from the Perplexity Blueprint direction, with seven values adjusted so every text pair meets WCAG AA 4.5:1.
   Page types scope the rules that differ: body.page-catalogue, .page-landing, .page-learn, .page-tool, .page-cert */
