/* FLOWING BLUE — the Fresco Panel. Document pages only: /en/news/*, /en/tws/.
   The film uses theme.css instead; this file deliberately does NOT inherit the
   scrub engine's injected CSS, because these pages never mount the engine.

   Requires tokens.css. Design rationale:
   2026-08-01-site-pages-migration-design.md §4

   A fresco is pigment on light plaster, so the plate is genuinely light and
   mounted on the dark wall. That is also what makes 400-word articles
   comfortable to read while staying inside the film's world. */
