/* ============================================================
   rp-ui.css — Reading Portrait's shared design language.

   One container dialect, six components, one signature gesture.
   Pages opt in by linking this AFTER styles.css/mobile-overrides
   and using the .rp-* classes; nothing here reaches into pages
   uninvited (every selector is namespaced).

   The dialect:
   · Surface: warm paper page (--page) → white cards → ink hero
     (reserved for the reader's identity alone).
   · Type: Josefin small-caps for LABELS, Lato for prose; italics
     only where a human voice speaks (letters, notes) — never UI.
   · Signature: the gilt double-rule (borrowed from the clothbound
     cover placeholder) as the recurring section flourish, and the
     book cover as the interface's atom.
