/* Coexa Layouts — Direction 4: "Ledger"
   An editorial, numbered-dossier read down the page: a persistent numbered
   spine (01 to 04), bracket-cornered callouts on key stat numbers, hairline
   rules dividing every section, big asymmetric display type. Built on
   Coexa's real dark canvas + the real violet to pink brand gradient, never
   a soft glow dashboard scene and never a grey/charcoal palette.
   Self-contained: every variable used below is defined in this file. */
