/*
 * ============================================================================
 * Retro BBS Theme — 6502ish
 * ============================================================================
 *
 * A retro terminal/BBS-inspired dark theme evoking green phosphor CRT monitors
 * and the golden age of bulletin board systems.
 *
 * All colours are defined as CSS custom properties in :root.
 * Monospace typography throughout for authentic terminal feel.
 *
 * Interactive elements use visible focus rings (3 px coloured outline + glow)
 * and meet the WCAG 2.5.5 minimum 44 x 44 px touch-target guideline.
