/* ── NEMI LMM brand (Brand Book v2.0) ─────────────────────────────────
   Space Grotesk carries voice, IBM Plex Mono carries data. One accent:
   Signal Emerald. No rounded corners; feature cards have the cut top-right
   corner. The sidebar is always Black Ground; the main area follows the
   theme (data-theme="light" on <html>, light by default). */
