The installer is not code-signed, so Windows SmartScreen will warn on first
run — More info ▸ Run anyway to proceed, or verify the hash above first. It
installs per-user, so it does not need administrator rights.

Windows only for now. electron-builder only builds for the platform it runs on,
and the macOS and Linux targets (DMG and AppImage) are configured but have not
been built or tested.

What it does

• Draw glyphs on a cell up to 32×32 pixels, with a draggable per-glyph advance
  width marker and Font ▸ Fit Width to Ink to snap it to the artwork.
• Five font-wide guidelines — cap height, x-height, baseline, and left/right
  column guides for drawing something like a 6x8 font on an 8x8 grid.
• Character map over codepoints 0–255, defaulting to CP437 with the SAM Coupé
  substitutions, with shift-click to pin a reference glyph behind the one you
  are editing.
• Undo/redo, glyph copy/paste, clear, invert, flip and shift, and a live preview
  of editable sample text.

Projects save as .fnt.json and round-trip losslessly. File ▸ Export Font…
writes a 1bpp .bin alongside .widths.json and .map.json sidecars; the exact
layout is in docs/file-formats.md,
and docs/user-guide.md
walks through the editor end to end.
