 * Mirrors the app's "Lit Stage" design system (2minsplank/DesignSystem.swift):
 *   - near-black canvas #050507, one cyan spotlight from above, faint ember counter-glow
 *   - one accent: cyan #00D4FF for actions, selection, links and progress
 *   - ember #FF7A2F for growth only (streak, XP); never chrome or buttons
 *   - outcome colors (success / warning) only for real status
 *   - Space Grotesk for display and labels, the system face for body copy
 *   - radius scale 8 / 12 / 16 / 20; neutral black elevation, no tinted glows
