   Crew Sheet — crewsheet.xymex.app
   Single shared stylesheet. No JavaScript, no external resources.
   System font stacks only. Dark-first with light via prefers-color-scheme.

   Palette is taken from the app itself: the accent is CuePhase.active
   (HSB 0.38/0.72/0.78) and the phase ladder below mirrors CuePhase.color,
   so the site and the product agree on what each phase looks like.
