"""The locker's pictograms: one place, so a glyph means one thing everywhere.

textgate (kuhy, 2026-11-08): nothing he sees carries words. Every screen is
built from these plus numbers, each paired with a palette colour as the
second channel (success / warning / danger / muted). Plain geometric
characters only: a colour-emoji fallback font can crash Tk 8.6, so no
U+1Fxxx and nothing with an emoji presentation by default.
