/* =============================================================================
   PALETTE — raw colour ramps. The base layer of the token system.
   =============================================================================

   SSOT: this file is the ONLY place in static/css where a colour literal is
   written. Every other stylesheet reads a semantic role from tokens/semantic.css,
   and semantic.css reads from here.

   Rules:
   * Nothing outside tokens/semantic.css may reference a --c-* value directly.
     If a component needs a colour, the role it needs is missing from semantic.css
     — add the role there, do not reach past it into the ramp.
   * A theme MAY override a ramp entry (that is what makes a dark or rustic
     palette possible) but may never introduce a bare literal of its own.
   * Ramp entries are named by hue and lightness step, never by usage. There is
     no --c-danger here; "danger" is a role and lives in semantic.css.

   Every value below is lifted verbatim from what themes/base.css already
   shipped, so introducing this file changes no pixel.
