/* ControlIQ demo — design tokens from the Lavoisier Labs v4 deck
   (lavoisierlabs/PITCH_DECK_V4.md, vertical-v5-2-canva.pdf) and lavoisierlabs.ai.

   Self-contained by requirement: no webfont fetch, no CDN. System stacks are used so
   the page loads instantly and works offline in a customer meeting; the exact deck
   faces can be swapped in at embed time by redefining --display/--body/--mono. */
