     THEME — "Ink & Slate", black & white surfaces
     Page/card backgrounds, borders and body text are strict grayscale
     (black on white) so the chrome of the app reads as a case file, not
     a brand. A deep, deliberately muted navy-slate is the primary accent
     (buttons, active states, highlighted values) instead of gold — kept
     serious rather than celebratory. Crimson is reserved for
     contradictions/alerts, verdigris for verified/OK, steel blue for
     neutral secondary categories — plus the chart series (--c1..--c6).
     Icons, badges, chips, stat tiles and charts should keep using these
     accent tokens unchanged; only the grayscale surface/text tokens
     above were touched.
