mangavalkandClaude Opus 5.5 0cf5df9b6e Add 3D-printable desk case for the VFD and a WEMOS D1 R1 
Parametric OpenSCAD design: 15 degree bezel holding the display on M3
heat-set inserts, slides into the body; base carries the board with the
DC jack and USB reachable through the back. Includes STLs, previews and
collision checks.

mangavalkandClaude Opus 5.5 95686a3608 Support every datasheet command and map text to the CG-ROM fonts 
- Brightness, blink, screen on/off, annunciators, cursor control, display
  modes, user-defined characters, code table, international charset,
  peripheral select, self-test, raw writes and reinit
- UTF-8 text is encoded with the selected code table (tables generated
  from Python codecs by tools/gen_charmaps.py), falling back to
  accent-stripping
- Settings survive reinit and the self-test
- Example gains brightness select and display switch, and uses the git
  source on mangavalk.com

The 20L203 input is RS-232 (reference build uses a MAX3232), it runs on
5-24 V, and it boots in non-scrolling overwrite mode.
