/* forge — one stylesheet, custom-property tokens, no framework.
 *
 * THEMING RULE (house convention, copy it exactly): the complete LIGHT palette
 * is defined on bare :root. Dark redefines only the tokens, twice — once under
 * prefers-color-scheme for the "system" setting, and once under
 * [data-theme="dark"] so an explicit choice wins in both directions. No colour
 * anywhere has its ONLY definition inside a media query; a token that exists
 * only in the dark block renders as nothing in light mode and the failure is
 * invisible until someone switches.
 *
 * The CSP is script-src 'self' / style-src 'self' with no 'unsafe-inline', so
 * there are no <style> blocks and no style="" attributes anywhere in this app.
 * Anything dynamic goes through the CSSOM (el.style.setProperty), which CSP
 * does not restrict.
