This is the latest progress on the e-ink support with HDMI support for debug.
Most of the work was done on v0.2.2 and there are md files in the directory covering the milestones and limitations in software and hardware of this project so far.

…tion

- Fixed post-image.sh to generate correct cmdline.txt for standalone SD boot (root=/dev/mmcblk0p2)
- Added clear comments in post-image.sh distinguishing SD standalone vs network boot usage
- Added full set of Pi4 reproduction and deployment scripts (pi4-rsh.sh, deploy-*, rsync, tftp sync, etc.)
- Included Phase 2 handoff documents (PI4_PHASE2_EINK_HDMI_HANDOFF.md and Phase 2.5)
- Added GUI responsiveness sprint documentation
- Added slowos_pi4_defconfig, updated genimage.cfg, and critical rootfs_overlay additions (S99zeink, eink-bridge, panel config, etc.)
- Added device-tree overlay (slowos-spidev-compat) and Phase 2 config.txt
- GUI responsiveness work from the same development period

This branch captures the complete e-ink-first + HDMI mirror development for standalone SD card use and handoff to other engineers.
