/* SIDRA Downloads — the approved portal design (v4, 9 September 2026).
 *
 * Source of truth: docs/design/downloads-portal-design-v4.html. Tokens, header,
 * rail, hero, buttons, file details, previous releases, edge pages and footer
 * are taken from that reference.
 *
 * Two mechanical differences forced by this app's CSP (default-src 'self',
 * which blocks inline style attributes as well as inline <style>):
 *   - the mockup's per-element `style="--d:.05s"` reveal delays are classes
 *     (.d1 … .d6) declared here;
 *   - .reveal runs as a CSS animation instead of a JS-toggled .visible class,
 *     so the entrance also works with JavaScript unavailable.
 *
 * Fonts stay self-hosted for the same-origin CSP: no CDN, no Google Fonts.
