/* LOCKED tokens — White Oak Dental (base system: wellness, bespoke-tuned)
   Tuned to a warm "white oak" green with a soft acorn-gold accent — a calm,
   natural wellness palette distinct from prior teal/lake-blue/sage/aqua-mint/
   sky-blue/seafoam/olive/slate/dusty-blue runs. Variable NAMES match
   _shared/base.css; only values changed. Contrast verified for AA:

   eyebrow brand-on-bg 5.75:1, card icon brand-on-tint 5.1:1. */
