     23/63/53) + Off White (digital: RGB 250/250/250) are the only two brand
     colors -- --ink/--paper are those exact values; --paper2/--paper3/--rule
     are surface/border tints derived from that same green-gray family
     instead of the previous unrelated warm cream/tan palette. The three
     status pairs below (review/unmatched/ok) encode verified/flagged/
     unmatched meaning, not brand identity -- the guide doesn't address them,
     so their hues are unchanged (--ok already sits in the same green family
     as the brand color, so it needed no adjustment for cohesion). */

  /* Graphik is BCI's brand sans (headlines/captions/details/body per the
     guide) -- a paid commercial font with no file in this repo, so this
     uses the guide's own documented fallback ("Arial is an adequate
     substitute for Graphik") rather than fetching/embedding anything.
     Louize (the brand's serif) is deliberately not used anywhere in this
     app: it has no natural "editorial body copy" role in a dense
     operational tool, and .display below is used on every screen's page
     title (not one hero moment), so serif there would be a much bigger
     typographic shift than a straightforward brand-color/font alignment. */
