   MARCHETTI & ASSOCIATES LLP · Client Portal
   Identity: "the engraved letterhead."
   Iron-gall ink chrome (sidebar · gate · mobile nav) around an ivory
   bond workspace · claret working ink · brass for matters awaiting,
   bay green for the settled. Marcellus (engraver's Roman — the
   letterhead face) · Albert Sans (UI) · DM Mono (docket metadata:
   MAT numbers, statuses, dates, amounts).
   Signature devices: the scotch rule (engraved double hairline),
   the ampersand seal, and the ink/bond chrome split.
   Distinct from Docket (court-form grey/oxblood pleading paper) and
   Countersign (kraft desk) — this is the stationery the CLIENT holds.
