/* VEXIUM — landing page.
 *
 * Only index.html uses this file. The legal pages (/privacy, /terms, /auth) keep style.css, so this
 * redesign cannot change a page someone may be relying on for its exact wording and layout.
 *
 * NO JAVASCRIPT, BY POLICY. web/_headers serves "/" with `default-src 'none'` and no script-src at
 * all: the reviewer console shares this origin, and a public page that runs no script is one an
 * attacker cannot use to reach a logged-in reviewer. Every motion here is CSS — keyframes on load,
 * and scroll-driven reveals (animation-timeline: view()) behind @supports, so a browser without them
 * simply shows the content, fully visible, with no motion.
 *
 * Fonts are self-hosted for the same reason (font-src 'self'): Exo 2, the app's own typeface, for
 * everything set in the brand voice; the platform serif for the one italic accent word per heading;
 * the platform mono for eyebrows and labels.
