   Buttons — the §7.1 correction lives here.

   OLD (demo): default tone = --ink (near-black), disabled = --lineHard bg +
   white text, measured 1.53:1 — reads as washed-out/inactive even when the
   button IS the primary action (see contrast_check.py).

   NEW: the primary action is unmistakably --brand-primary (green) always —
   matching the brief's own §4 role definition ("brand-primary... primary
   CTA"). Verified 6.25:1, comfortably clears AA. The old default `ink` tone
   survives as .lsl-btn--secondary for genuinely lower-emphasis actions (e.g.
   the demo's PDF-export buttons). Disabled gets its OWN token pair
   (--cta-disabled-bg/-fg) distinct from both, so it can never again share a
   value with a border or an enabled state — verified 3.53:1, and WCAG 1.4.3
   exempts disabled controls from the AA floor entirely, but this still reads
   clearly rather than vanishing the way the old 1.53:1 pairing did.
