/* ==========================================================================
   Floow — shared design system (floow-trace.ai)
   Ported from the dune-labs.ai S1.1 shell; re-themed to Floow's brand.
   Single source of truth for tokens + shared components. Loaded on every page
   with the Tailwind CDN (Tailwind = in-body utilities; this = brand + shell).

   BRAND IS LOCKED (Califraj Studios pack v1, 2026-08-28). Colours + type below
   are a DERIVED RENDER of the canonical tokens note — swap values only if the
   pack changes (never edit to match code).
   Canonical: Portfolio-Brain/00-Substrate/design-system/floow-brand-tokens.md
   Dual-mode (light/dark) per the tokens note's "Dual-mode contract": semantic
   tokens in :root (light default), overridden under @media (prefers-color-scheme:
   dark) AND html[data-theme="dark"]; the accent is mode-independent. All values
   are canonical or an alpha/color-mix derivation — no invented hues.
