/* @theme riprap
 *
 * Marp theme that mirrors the SvelteKit UI's design tokens 1:1.
 * Civic Hydrology palette (v0.4.6, 2026-05-06): USWDS federal blue,
 * cool slate register, deep navy synthesis. Replaces the warm-paper +
 * burnt-orange register that read as editorial / Anthropic-adjacent.
 * IBM Plex Sans drives display + body; serif retained only for the
 * single hero quote-mark on slide 7. Layouts are box/grid framed —
 * the deck reads like a dashboard, not an essay.
