   "A cool, clinical base. One calm accent."
   Cool neutrals do the work; the muted teal accent appears only
   where it carries meaning. Caution is a desaturated amber, used
   sparingly, never dominant. Nothing is alarmist — destructive is
   a muted clay, never red.

   Two themes:
   :root              -> Light
   [data-theme=dark]  -> Dark · "overcast night" (deep blue-charcoal,
                          never pure black; same calm mood, lights down)
