 * Responsibility: shared design tokens and components. v3: rebuilt to
 * replicate the UI/UX specimen the user provided for the Quest
 * Calculator — same underlying colors as v1/v2 (the hex values are
 * identical), extended with semantic tokens the specimen introduced
 * (--good, --bad, --muted, --line, --line-soft, --surface-hover) and its
 * component language (bordered pseudo-tabs, .panel/.panel-heading/
 * eyebrow, .status-note, .source tags, chips, progress bars, a reusable
 * modal, toast). --font-pixel keeps 'Press Start 2P' as the primary face
 * (the one hub-wide identity element established across this project)
 * with the specimen's Courier New as its own fallback before monospace.
