/* ============================================================
   lk-main — Lyrikai Public Surface Component Layer

   Composes on top of the canonical Lyrikai stylesheet
   (lyrikai-os/lk-styles/styles/lk-exp-2/styles.css), which
   defines all --lk-* tokens. layout.ts loads canonical first, then
   this file. Per Section 11:

   - Do NOT redefine --lk-* tokens here. Canonical owns them.
   - Pre-Section-11 --lkos-* tokens are kept as a file-local
     compatibility namespace. Tokens with canonical equivalents are
     aliased to var(--lk-*) so the entire palette responds to canonical
     theme switches automatically. lk-main-specific tokens (logo glow,
     neon, grid wash, etc.) keep their original literal values.
   - A future hygiene PR will rename --lkos-* references inside this
     file to var(--lk-*) where canonical equivalents exist, and rename
     truly local tokens to a --lkmain-* namespace.
