/* =========================================================================
   PRFactory — Color tokens (the ONLY dual-palette token file)
   Values copied verbatim from the chosen mockup
   C:\temp\PRFactory\mockups\06-developer-dark-dual\styles.css
   (dark :root L18-79, light overrides L154-220).

   Theme resolution (Epic 17 owner decision, no JS / no <script>):
     1. Default (no explicit user override): CSS prefers-color-scheme.
        Dark is the canonical :root; light is applied when the OS asks
        for it via @media (prefers-color-scheme: light).
     2. Explicit user override: a [data-theme="dark"|"light"] attribute
        emitted on <html> server-side from the prf-theme cookie. The
        attribute selectors below have higher specificity than the
        media-query block, so an explicit choice always wins the cascade.
   No gradients in either mode — flat fills only.
