 * Brand-color shift. Every participating element runs the same 60s keyframes on
 * its own timeline — reliable in all engines. (Animating one inherited custom
 * property instead is a Chromium-only trick: Firefox/Safari never repaint the
 * descendants that read it via var(), so the whole page freezes on one color.)
 * Elements present at load start together; ones added or toggled active later are
 * re-phased onto the shared wall-clock cycle by initColorShiftSync() in app.js,
 * so nothing drifts. Keyframe colors are literal (mirroring --sf-ai-brand-1..4)
 * and set both fill and background-color, so one animation drives the SVG logo,
 * the architecture rects, and the div backgrounds alike.
