/*
 * slvnt.cloud — the public site.
 *
 * The `--ledger-*` block below is copied verbatim from ledger-auth's
 * `auth.css`, which is the canonical source (D19/D20). ledger-ui mirrors the
 * same values as Angular Material tokens. That makes three copies, and the
 * rule that comes with them is "change one, change all three".
 *
 * So: do not add a colour here. Every value this page needs already exists in
 * that set, and a fourth colour invented for a marketing page would either
 * break the pairing or grow a shared surface across two repositories for no
 * domain reason. The one thing auth.css genuinely lacks is a layout scale —
 * it only ever renders a 26rem centred card — and that goes in the separate
 * `--site-*` block, deliberately outside the shared surface, exactly as
 * ledger-ui keeps its `--app-*` scale out of it.
