/* ===========================================================================
   Legal document stylesheet — uncommonweather.com
   ===========================================================================

   The 53 documents under /legal/ are hash-recorded in an append-only ledger:
   their bytes are quoted in acceptance receipts already issued to real users,
   so not one of them can be edited. They were authored expecting a stylesheet
   at /styles.css and a mark at /assets/uncommon-weather-mark-{32,64}.png. On
   the v3 deploy those paths 404'd, which is why every terms page, privacy
   policy and product schedule — the pages the App Store, Chrome Web Store and
   Gumroad link to — rendered as raw unstyled HTML with a broken image.

   So this file is written to fit the markup they already contain, rather than
   the markup being changed to fit a new design. It is the one lever that moves
   all 53 without touching a hashed byte.

   Their markup is genuinely good: .legal-hero, .legal-layout > .legal-copy +
   .legal-nav, .eyebrow, .lead, .legal-meta. It only ever needed dressing.
