/* TAK Self-Enrollment Portal — base styles.
 *
 * Every visual choice (color, font, radius, etc.) is a CSS custom property
 * declared on :root. A deployment that wants to skin the portal in their
 * own brand only needs to override those properties — no template edits.
 *
 * Where to override:
 *
 *   1. Drop a branding.css file into the SE assets directory. The
 *      template auto-loads it AFTER styles.css when the metadata field
 *      PORTAL_BRANDING_CSS is "true" (default). Anything redefined in
 *      branding.css wins by cascade order.
 *
 *   2. For one-off color tweaks without a separate file, set
 *      PORTAL_ACCENT_COLOR in the SE metadata block — the template
 *      injects it as an inline <style> overriding --accent.
 *
 *   3. For typography, override --font-stack via PORTAL_FONT_STACK
 *      metadata (e.g. "'Inter', system-ui, sans-serif").
 *
 *   4. For the page logo, set PORTAL_LOGO_URL metadata. The template
 *      renders an <img class="brand-logo"> in the header when this is
 *      non-empty.
 *
 * Branding branch: the future branding work lives ENTIRELY in branding.css
 * + logo image asset + a few metadata fields. No Go changes, no template
 * structural changes.
