   Cor Portal v2 - shared long-read stylesheet.
   Used by the linked long-reads: bridge-paper.html ("The Optimizer Without a

   classes are namespaced .lr-* per IA-BUILD-CONTRACT sec.3. Loads AFTER

   warm parchment ground, oxblood Spectral display serif, teal+gold accents,
   JetBrains Mono meta, diamond rules, the signature offset hard double-shadow.
   Do NOT invent a new look.
