/* ============ FIRSTHAND — DESIGN SYSTEM ============
   Visual thesis: an operator's "Mission Control" rendered on paper.
   Two variants share one structure: LIGHT (default, editorial, precise,
   high-trust) and DARK (the original control-room aesthetic). One signature
   accent (signal orange), one telemetry green for proof.
   Type: Unbounded (display) · IBM Plex Sans (body) · IBM Plex Mono (data).
   Shared across homepage + service pages. Single source of truth.
