/* ============================================================================
   Design system — "working paper"
   (The practice name lives only in src/content/site.js — do not put it here.)

   ⚠️ THIS SITE DELIBERATELY DOES NOT FOLLOW the "what makes a site look 2026"
   recipe in PLAYBOOK.md, and the departure is the point. Three sites in this
   folder implemented that recipe and became indistinguishable from each other:
   the same Playfair Display / DM Sans pairing, the same warm off-white ground,
   the same white cards. This file used to say "tokens adapted from
   thelocalcard" and 21 of its 31 tokens were byte-identical to that project's.

   KEPT from the playbook:   self-hosted fonts, one accent colour, entry motion,
                             dark mode, fluid type, hairline separation.
   REJECTED on purpose:      display serif, white cards, large radii, layered
                             depth, generous banding, the serif-italic eyebrow.

   The brief instead: a statistical working paper. A text serif for everything,
   a monospace for labels, dates and captions, rules rather than boxes, and a
   denser vertical rhythm than a marketing site would use.

   TWO COLOURS, and they do different jobs. Oxblood #7A2E2E is the accent —
   links, buttons, figure lines — a printed-report colour, and unlike the teal
   it replaced it is not within 18° of hue of a sibling project's green. Brown
   #6F6151 is the brand: the header and footer grounds, the 2px rules that
   bracket them, and every hairline in between. The page itself is a warm cream
   rather than the near-neutral off-white the other projects share.

   ⚠️ The brown is a GROUND and a RULE colour, never a text colour. See the note
   on --muted before using it for anything small.

   Do not restore Playfair Display or DM Sans. Do not reintroduce cards.

   ⚠️ Source Serif 4 is VARIABLE (wght 200-900), IBM Plex Mono is NOT. There is
   no variable cut of IBM Plex Mono anywhere — the Google css2 API returns 400
   for it, the fontsource variable package does not exist, and both the IBM npm
   package and google/fonts ship static files only. So the mono is two static
   weights, and its descriptor must be format('woff2'). Copying
   format('woff2-variations') down from the serif blocks makes some engines
   discard the whole @font-face, and the symptom — small uppercase letterspaced
   Courier — looks almost deliberate.                                     ---- */
