   THE KNOWLEDGE LIBRARY — the index, the article page, the thumb, and the script viewer.

   Written in the tokens only, so the five palettes and the dark theme come for free: since
   09/10/2026 theme.css redefines --panel, --line, --ink, --brand and --a1 per palette and per
   theme, and site.css the three fixed accents and the state colours. The code colours are no
   exception any more: the highlighter's tones are the fixed accents, the danger red and the
   brand, all drawn to hold on both grounds, so a script reads in every palette and theme.

   One prefix per job, so a rule can be found by its name: `kb` for the library, `sv` for the
   script viewer. Rules the free tools already define (.panel, .notice, .disclaim, .tbtn) are
   not repeated: an article loads tools.css beside this file.
   --------------------------------------------------------------------------- */

/* THE CHAMFER, on this library's own pieces: the cut site.css gives its plates and tags, with
   the same polygon and the same `corner-shape` variant. Each piece below carries a fill, never a
   border, for the reason site.css gives — a clipped border loses its diagonal. */
