/*
 * DoYouTax design tokens (tickets 0003, 0103 and 0105, docs/design/systeme.md).
 * Shared by the site (site.css) and by the print templates rendered with WeasyPrint
 * (print.css). Hand-written, no build step.
 *
 * Second execution of the art direction (ticket 0237, sub-lot B1): direction D, the free
 * design chosen by Antoine on 2026-10-14 (docs/design/direction-2026-10/d/). Since ticket
 * 0271 (Q232 (a)), one palette: the block `:root` carries the colours and the families of
 * direction D for every rendering (screens, delivered documents, e-mails, social card,
 * figures), under the roles of docs/12; the block `:root.site`, below, keeps only the
 * shapes and the focus of the screens (the element `html` of templates/base.html carries
 * the class). apps/core/design_tokens.py reads both blocks and measures every pair of
 * docs/12 in each. Every colour variable is covered by the contrast test
 * (apps/core/tests/test_design_tokens.py): a new colour needs a pair there.

/* Fonts (ticket 0103): DoyouTax Serif, DoyouTax Sans and DoyouTax Mono are Latin
   subsets of Spectral, Hanken Grotesk and IBM Plex Mono, renamed so that no modified
   file carries the name of the original (SIL Open Font License 1.1, condition 3 for the
   Reserved Font Name "Plex"; scripts/subset_fonts.py, static/fonts/LICENSE-*.md). The
   family names are identifiers and keep the spelling of the preloaded files. Served
   from static/fonts only: no font is ever loaded from another domain. Since ticket 0271
   they serve the figures drawn by the code (`--font-drawn-sans`, `--font-drawn-mono`)
   and the social card (TTF subsets of the same files, server side); the documents, the
   e-mails and the screens are set in the families of direction D below. */
