/**
 * AI Society, Landing page styles.
 *
 * MOBILE-FIRST. Every base style targets a 320 px phone. Width-up media
 * queries (`@media (min-width: ...)`) add the desktop expansion. Fluid
 * sizing via clamp() handles the in-between viewports without breakpoint
 * jumps. Touch targets are ≥ 44 px. Section and hero spacing scale with
 * viewport width so the page is dense on a phone and breathing on a desk.
 *
 * Extends (does not replace) the kit's --twc-* tokens by defining a
 * project-scoped --ais-* layer. Page-level color/spacing references use
 * --ais-*; cross-cutting kit components keep --twc-*.
 *
 * Hard rules respected:
 *   - No raw hex outside :root token definitions.
 *   - Max font-weight is 500 (kit hard rule #7 spirit).
 *   - The pastel multi-blob hero gradient is the *only* approved gradient
 *     (project CLAUDE.md §7 exception).
