Theme Name: BitVolts Lab

/*
 * Managed in git (Infra/stacks/wordpress/theme/bitvolts) and mounted read-only:
 * edit it there, not in WordPress. Colours/fonts come from theme.json; this file adds what
 * theme.json can't express: dark mode, the Docusaurus-like navbar/footer and the neon touches.
 * Mirrors src/css/custom.css of the main site — keep both in sync.
