/*
  Design decisions (R-31):
  - Dark blue-gray base: requested by the owner; it also keeps a phone readable at night.
  - Blue (#5ea8ff) is the single action color: primary buttons, focus, links.
  - Cyan (#3fd6b4) only means "available / done": meters, filled team nodes, success.
  - System font stack: legible on every phone and needs no CDN, so the page works offline from external hosts.
  - Motif: the four-node team spine beside the member pickers, and 11-cell meters showing real counts.
  - Shadow only on the dialog and the open option list, the two layers that sit above the page.
