  /* ROOM3 Threshold brand kit — dark family only (this app has no light theme).
     Mapping (kit token → app var):
       Ink        #151713 → --bg-base, --on-accent
       Rule-dark  #2D312C → --bg-raised
       Threshold  #677064 → --bg-chip (as a 28% tint, so it still lifts off
                            both Ink and Rule-dark; solid it is too light for a
                            surface and only 3.5:1 on Ink, so never text)
       Surface    #F2F1EB → --text, --text-chip; hairlines as 8% / 16% tints
       Muted-dark #A5ADA2 → --text-muted, --text-faint (the kit has one muted
                            tier on dark; Threshold fails AA as small text)
       Accent     #A8F23A → --accent. A signal, not body text: fills carry Ink
                            text (13.2:1), otherwise rings, borders, dots, icons.
       Danger     #E05A4F → --danger-bg / --danger-border tints; --danger-text
                            keeps its lighter tint (#E05A4F is 3.6:1 on
                            Rule-dark, below AA for the drawer's danger row).
