/* ==========================================================================
   Theme: warm monochrome editorial, adapted from the NOCTRA reference.
   Cream/bone on near-black (dark, primary) — inverted to dark-on-cream (light).
   NO colour accent: the design is strictly warm monochrome. Structure comes
   from fine hairlines, boxed/bracketed controls and generous space.
   Signature motifs: the animated 3D pixel-computer wordmark, ✶ section
   labels, [↗] arrow-in-a-box "open" affordances, cream/dark fill buttons,
   bordered mosaic cells with duotone (grayscale+sepia) covers.

   Type: JetBrains Mono (ALL chrome — nav, meta, labels, footer, code; UPPER
   tracked), Redaction 35 (big display titles), Newsreader (clean serif —
   cell titles, prose headings), Paprika (wordmark), Geologica (post reading
   body only — the user's pick). All self-hosted, strict CSP.
