   gate.css — gate-SPECIFIC pieces for the fulfillment + KB pages, layered on
   css/tokens.css + css/components.css. Only what the component library doesn't
   already provide: the navy hero band with the gold rule, keyset/file rows,
   version tags, preview banner, admin type-ahead, saved-ID lists, KB steps,
   and print rules so keys/files pages print clean.
   Charter: dual-tone --focus comes from components.css (never overridden),
   44px+ targets, state never by color alone, fluid to 320px.
