/*
 * Vector — design tokens & site shell.
 *
 * THE RULE THIS FILE EXISTS TO ENFORCE: canvas.flow-field is a fixed,
 * full-viewport layer that persists behind every section on every page —
 * never rebuilt per-section, never covered by an opaque background. Every
 * section here is deliberately transparent or lightly glass-tinted so the
 * flow field reads through continuously as you scroll, not just in the
 * hero. If you're adding a new section, its background MUST stay
 * transparent/glass — an opaque section background silently defeats this
 * theme's entire premise.
