/* Merkzeichen — the telc B1 visual memory system (design-system/README.md is the spec).
   Four signals, each with ONE meaning everywhere:
   1 Teil      = number + colour + shape   (1 blue circle · 2 green triangle · 3 orange square · prep dashed ring)
   2 Connector = where the verb goes       (weil purple ⇥ end · und/aber ink = normal · deshalb red ↷ next)
   3 Marker    = yellow = the only words you change (used for nothing else)
   4 Module    = icon + name, no colour of its own (colour belongs to the Teile) */
