 * Nearly all design tokens live in theme.json. This file only carries what
 * theme.json cannot express: the CRT overlay, motion, focus behaviour, the
 * sticky/fixed nav chrome, and the layout primitives used by the patterns.
 *
 * GLYPH CONSTRAINT: the bundled JetBrains Mono subsets cover latin +
 * latin-ext only. Box drawing (U+2500..), block elements (U+2588..),
 * dingbats and geometric shapes are NOT in the subset and would fall back to
 * a system font mid-line. Every rule, cursor, bullet and LIVE dot below is
 * therefore drawn with CSS, and prompts use plain ASCII '>' and '$'.
