/**
 * Single-cell symbols, with ASCII stand-ins for terminals that cannot draw them.
 *
 * A glyph a font lacks is not a small cosmetic problem: the Windows console renders U+A7B0 (the
 * turned K in KONECK's mark) and U+276F (the prompt caret) as replacement boxes, so the brand read
 * as "⊡K" and every prompt line began with a box. Box-drawing characters are fine there, which is
 * why the panels looked right and only these did not.
 *
 * Detection is by platform rather than by probing the font, because there is no reliable way to
 * ask a terminal what it can draw — and guessing wrong in the optimistic direction is what produced
 * the boxes. Windows Terminal with a modern font would manage the originals, but it cannot be told
 * apart from the legacy console, so Windows gets the safe set and anyone who wants the originals
 * can say so.
