/* ═══════════════════════════════════════════════════════════════════
   MangaBest Reader

   Design brief: the images are the content, so the interface gets out of
   their way. Near-black with a slight cool cast rather than pure #000 —
   pure black next to a bright manga page produces a harsh edge and makes
   the page look like it is glowing. Accent colour is admin-configurable
   and injected as --mbt-accent, so it is used only where a decision is
   being offered, never as decoration.

   No webfont. On a page whose LCP is a 900KB manga scan, a font request
   competes with the thing the reader actually came for.
