/* FORMAT//LAB Academy — /examples/format-lab-academy/
 * From Gordon's format-lab-academy.zip (style.css), 2026-10-29.
 * Changes for bozcode: the Google Fonts @import is gone (CSP font-src 'self'
 * blocked it), Manrope -> Inter and DM Mono -> JetBrains Mono, both from
 * css/fonts.css. The bozcode additions are at the bottom.
 * 2026-10-29: switched to a LIGHT theme (Gordon: "I can barely read it. It is very
 * dark") — navy ink, logo-blue accent, every colour in :root or mapped from the
 * old dark literals; small text sizes bumped 1-2px. All pairs >= 4.5:1. */
