/* ============================================================
   TERMINAL-HYBRID THEME — Mono Chrome + Serif Prose
   
   Design DNA:
   - Mono for all UI chrome (nav, labels, dates, tags, sidebar)
   - Serif for body prose and headlines (reading surface)
   - Three-column layout: gutter | spine (~720px) | sidebar
   - Accent blue terminal style, with bento-inspired accent cards
   
   Status: Primary theme. Grid and editorial are legacy references.
