The braille base map and its labels lean on Unicode a terminal font may not
have: 8-dot braille (U+2840-28FF) that many fonts omit, and place/node names
in scripts or emoji outside a Latin monospace font. A missing glyph renders as
double-width tofu, which both looks wrong and shoves the panel right border.
- Prefer a romanized name (name:latin/name:en) over the local script, and strip
labels to single-cell characters, so foreign names and emoji node names can no
longer tofu or knock the grid out of alignment.
- Add a block-element base-map mode, toggled with t: 2x2 quadrant blocks instead
of 2x4 braille - half the vertical resolution, but glyphs essentially every
monospace font has. Braille stays the default.
- Zoom with PageUp/PageDown as well as +/-.
- While braille mode is active, force a full repaint each paint so the
double-width-fallback corruption on the right border is scrubbed on every move.
