/* ==========================================================================
   HomeRuleCheck — style.css  (v2, desktop-first redesign)
   Design direction: "official determination" — the civic act of looking up
   a permit / inspection / disposal ruling, rendered as a fast, premium tool.
   Signature: the verdict tag, styled like a physical tear-off permit stamp.
   Type identity: a strong sans for headings + a monospace utility face
   (evoking typed municipal records) for eyebrows, labels, statuses, data.
