/*
 * Calm Story Narrator — the single stylesheet, mirroring DESIGN.md.
 *
 * Warm minimalism: warm neutrals (never blue-gray), whisper borders, restrained
 * shadows, one saturated accent reserved for the primary action. Two modes share
 * these tokens: the dashboard a parent manages, and focus mode, which is
 * deliberately stripped to one button and one sentence.
 *
 * Nothing animates. Transitions are disabled outright rather than merely toned
 * down, because a child's screen should never move on its own.
