   speakeasy.css — CANONICAL speakeasy design SYSTEM (tokens + components).

   Self-contained: @imports the token layer, then the robust, content-agnostic
   component library (relocated verbatim from pseo.css, so the pSEO corpus renders
   byte-identically). Consumed by:
     • site/css/pseo.css  →  @import url('speakeasy.css');   (301 pSEO pages, links unchanged)
     • Phase 2+ reskinned pages  →  <link rel="stylesheet" href="/css/speakeasy.css">
   The homepage links speakeasy-tokens.css instead (it owns its own components).
