/* ============================================================
   RomanceLab — "Clinical Paper" design system
   ------------------------------------------------------------
   Concept: one lab coat in a room full of scented candles.
   Institutional register: IBM Plex Sans + IBM Plex Mono on warm
   paper with graphite hairlines. The warmth is typographic – the
   Exposed register (compounds, findings, the true thing) switches
   to Newsreader. One "exothermic" accent, spent like a rare event.
   House style: spaced en dashes, never em dashes.
