/* =====================================================================
 * MarpaMail landing homepage -- styles for this page variant.
 *
 * Loaded by homepage.tpl beside this file, so these rules only ever apply to
 * the homepage. Nothing here belongs in css/custom.css.
 *
 * Built only from PHOX's own custom properties (--brand-primary, --block-bg,
 * --radius, --spacing-Nx, --text-heading-color, ...), so the brand colour and
 * html.wdes-dark-mode are inherited without a second set of rules.
 *
 * Sections stay inside the .container that header.tpl wraps main-body in.
 * A full-bleed hero would need a 50vw break-out, and vw includes the
 * scrollbar on Windows, which yields a horizontal scrollbar on the whole
 * page. The rounded hero panel avoids that class of bug entirely.
 *
 * color-mix() is written directly in each declaration rather than behind a
 * custom property: through a var() indirection an unsupported color-mix makes
 * the declaration invalid at computed-value time (resolving to `unset`)
 * instead of falling back to the plain-colour declaration above it.
 * ===================================================================== */
