/* Tripcerto internal — the site's one stylesheet.
 *
 * ⛔ THIS IS THE ORIGINAL DESIGN, LIFTED VERBATIM. A rebuild in the status page's visual language
 * was tried and rejected: that page is a public dashboard and reads as one, which is wrong for a
 * set of documents somebody has to sit and read. Nothing here should be "refreshed" — the split
 * into per-document pages and the build step are the change; the appearance deliberately is not.
 *
 * ⚠️ Linked, not inlined. Pages are generated by scripts/build-internal-site.mjs, so a change here
 * reaches all of them at once; at twenty-plus documents an inlined copy is a change made twenty
 * times. Consequence to keep in mind: a single .html opened from disk renders unstyled. The site
 * is served and access-controlled — if a document has to go to somebody, export a PDF.
