/* Carabel marketing site — shared design system.
 *
 * One stylesheet, no build step. Tokens follow DESIGN.md's warm-gray light
 * palette plus two AA-driven additions (#0F766E teal-text, #1D4ED8 blue-hover)
 * and the marketing radii set (10px controls / 16px cards) — both logged in
 * DESIGN.md's Decisions Log (2026-07-09). Light-only by decision (scope G-6).
 *
 * The specialty avatar colors (.av.*) duplicate apps/agents/specialty_palette.py
 * deliberately: this static site cannot read Python. That file is the source
 * of truth; if the palette changes, update the hexes here.
