/* ==========================================================================
   Attest — review desk for clinical dossiers
   Design notes
   - Subject: regulatory review of clinical documents. The vocabulary is
     ledgers, marginalia, stamped dispositions, section references, hairlines.
   - Palette: cool mineral paper and petrol ink, with four evidence colours.
     Deliberately not warm cream, not near-black with an acid accent.
   - Type: Newsreader carries the document and display voice (a serif that
     reads like a typeset report); Archivo carries the interface; Plex Mono is
     reserved for identifiers, thresholds and anchors, which are data.
   - Layout: registers with a margin column, not a grid of cards. One bold
     gesture: the completeness fingerprint, which draws once per analysis.
