/*
 * Velsigil website - the only stylesheet.
 *
 * Same identity as the panel (web/src/index.css): near-black surfaces, hard edges (0-4 px radius), 1 px
 * borders, one violet and one magenta from the logo, used sparingly. 45-degree corner cuts ("blade cuts",
 * like the panel's sidebar plate) are the signature motif; they are drawn by pseudo-elements BEHIND the
 * content, so no clip-path ever cuts a focus outline. The violet -> magenta gradient appears only in the
 * logo, in 1 px rules and on the edge of a few highlighted plates.
 *
 * Dark is the default; prefers-color-scheme: light switches the tokens. No JavaScript, no inline styles
 * (the Content-Security-Policy is style-src 'self').
