/* ---------- Why there are separate "ink" tokens ----------
   Gold is a fine decorative color and a poor text color on a near-white page.
   On the light surfaces, --gold (#8A6B1F) measures 4.71:1 on --card, 4.38:1 on
   --paper and 4.33:1 on --badge-bg — at or under the 4.5:1 AA floor, and it was
   carrying the *smallest* type on the site (11px mono, uppercase, weight 400–500).
   Borderline contrast on tiny tracked-out monospace is what made the labels read
   as thin and washed out. --muted (#6B6F63) sat in the same band: 4.46–4.85:1.

   Rather than darken --gold and --muted globally — which would also darken every
   hairline, bar and focus ring and change the page's whole temperature — text use
   is split onto its own tokens. Decoration keeps the original values; text gets
   deeper ones. Light: --gold-ink 7.86–8.55:1, --muted-ink 7.09–7.70:1.
   Dark was already comfortable (gold 7.74–9.28:1) and is left on the same hue;
   only --muted-ink is lifted, from 4.74–5.69:1 to 6.64–7.97:1.

   --muted-ink is a SLATE, not a darkened --muted. --muted is warm (hue 80deg,
   yellow-green) because it belongs to the parchment/hairline family. Darkening it
   in place kept that cast, so the footer and captions read visibly gold-tinted
   against the page's cool slate body copy. --muted-ink is pulled onto --body's hue
   instead (216deg vs --body's 213deg) at lower saturation — it now reads as a
   lighter sibling of the body text rather than a different, warmer ink.

   Rule of thumb: --gold/--muted for anything you cannot read; --gold-ink/--muted-ink
   for anything you can.
   ---------------------------------------------------------- */

/* ---------- Type scale ----------
   Every piece of PROSE AND UI TEXT resolves to one of these five steps, so
   secondary text in one section cannot drift a half-step away from secondary
   text in another. Before this the page used .7/.75/.8125/.875/.9375/1/1.0625/
   1.125rem with no rule about which meant what, and near-identical sizes landed
   on elements of equal rank (the eyebrow at .75rem beside sibling labels at .7rem).

   Deliberately outside the scale, and staying that way:
     h1 (clamp) and h2 (1.375rem) — serif display type, sized against the layout
       rather than the body copy;
     #theme-toggle (1.05rem)      — sizes a glyph, not text;
     .sample-record (.8125rem)    — preformatted code whose line width drives
       horizontal overflow, so it is sized against its container.

   --fs-label  mono micro-labels ONLY (uppercase kickers and field labels)
   --fs-fine   fine print: captions, footer meta, citation block
   --fs-small  secondary body: trust strip, callouts, footer prose
   --fs-base   body copy
   --fs-lead   lead-ins: subhead, response note

   Rank is carried by color and weight, not by size — hence the deliberately
   tight steps at the top of the scale. Mobile shifts the tokens, not the rules. */
