/* ============================================================================
   Cor Portal v2 - cases surface (.case-*)
   Layers on tokens.css + portal.css. Long-read / case identity, inherited
   verbatim from the Cor look: warm parchment, oxblood Spectral display, teal +
   gold offset hard double-shadow, JetBrains Mono eyebrows, diamond accents.
   These are reading pages - a single narrow column, no new look invented.

   IMPORTANT: the static "case-resolution" block echoes the proxy / resolution-
   conditions framing in PROSE only. It deliberately does NOT animate, drain, or
   imitate the interactive gradient stage - that interaction is inviolable and
   lives only on mechanism.html.
