/* EB Construction — website

 * THE BRAND CHAIN. This file imports the design system's tokens and never
 * declares a color or typeface of its own. `python3 tools/gates.py` fails if a
 * raw hex or literal font-family appears below.
 *
 *   assets/brand/*.pdf → design-system/tokens/*.css → css/site.css → website/index.html
 *
 * Structure and motion follow the reference Will supplied: fixed nav,
 * full-viewport hero over moving media, a light statement section, and a
 * bento grid. The reference's opening splash is deliberately gone — the site
 * lands directly. The palette does NOT follow it — the brand contract allows one
 * accent, so where the reference punches with orange this punches with white on
 * navy, which the guidelines explicitly sanction.

 * phone edge or on `pointer: coarse`, which no mouse-driven browser reports.
 *
 * The phone is not a narrow desktop. Three things genuinely have to change
 * shape rather than just shrink:
 *
 *   1. The stage. At 402px the headline, the note and the EB mark all land on
 *      top of each other inside the panel, and the CTA falls across the
 *      chamfered corner where the navy has been cut away — putting a white
 *      square on the white ground. The panel becomes a plate and the copy
 *      runs underneath it, in document order.
 *   2. The client films. Four 16:10 tiles stacked is ~950px of scrolling to
 *      get past three logos. They become a swipeable rail.
 *   3. The founders. Three full-width headshots is ~1250px of face. They
 *      become a row of three.
 *
