/* Trowelscape — brand tokens pulled from the LUXE Surface Finishing Design
   System identity sheet (Trowelscape Identity.dc.html): warm charcoal/sand/
   bronze palette, the trowel-blade-over-a-swept-horizon mark, Fraunces as
   the light-weight display face for the wordmark and page headlines.
   Exact hex values are our best match to the named tokens (--char-900,
   --sand-100, --bronze-500/600, --stone-600, --border-hairline) — the
   identity sheet only links to the design system's own token files, which
   weren't fetchable here. Swap these for the resolved token values if the
   real stylesheet becomes available. */
