"""The PC gate's glyph vocabulary: one shape per concept, no words.

kuhy's textgate rule (2026-11-08): nothing the gate paints carries a word.
Every Tk surface draws from this one table so a concept looks the same on the
Log Meal, History and Body tabs. Plain geometric BMP characters only, all in
DejaVu Sans: colour emoji can crash Tk 8.6 and the gate is the one window
that must never fail to draw. ``test_gate_no_words`` is the guard.

The macro shapes match the phone app's ``MacroKind`` (protein circle, carbs
triangle, fat square), so one vocabulary reads the same on both devices.
