/* ===========================================================================
   Selo — "Sealed Horizon" stylesheet
   A toned-down, professional take on Kora's Pacific Horizon language for a
   confidential investor data room: light-first, Onest variable sans (no serif),
   teal as the single action accent, ocean/deep for structural gravitas and the
   wax-seal motif, horizon amber/coral reserved strictly for tier identity.

   Token model: this :root defines the full palette. ThemeStyle.razor (document
   head) overrides only the tenant-themeable subset (--accent, --bg, --surface,
   --ink, --muted, --line, --font-sans) for white-labelling, and follows this
   file in the cascade so its values win when present.
