 * SchoolPick design tokens.
 * Phase 0: color/type bridge.
 * Phase 1: surface language — interactive vs informational elevation.
 * Phase 2: theme-aware bump chart series palette (--sp-chart-palette).
 * Phase 3–4: brand blue (#009BFF) from logo pack + login atmosphere.
 * Phase 6: app chrome (ink navbar, page canvas, tap targets) without a rebrand.
