/*
 * Mars 3D Map - HUD, stage and article. ASCII only.
 * Palette and type are fixed by CONTRACT.md (muted v1.1 palette). Text always
 * sits on a solid container; white text on red is never used below 24px (red
 * carries black text); everything is uppercase except the article body, the
 * tooltips and the control hints. Accent fills are reserved for active or
 * primary states; headers are dark bars with an accent rule.
 * Animations are slow, low-contrast transform/opacity only (plus the one-off
 * boot reveal and the info-panel wipe). prefers-reduced-motion switches every
 * decorative animation off at the bottom of this file.
