/* Teaology POS: shared look for the counter, the kitchen screen and the admin.
   The Teaology shop app's colours and fonts (Member Card palette, Figtree + Walone) with its plain
   working-tool finish: hairlines instead of boxes, 6-8px corners, no shadows except on what floats,
   states as a dot and a word, underlined tabs. One accent (Teaology blue); navy for the brand. */
