document display architecture research and settled design decisions
...
- eDP direct connection ruled out: undocumented pinouts, voltage mismatch risk,
community consensus favors controller boards
- MIPI DSI ruled out: 2-lane 15-pin, can't dual-display with HDMI on Linux,
and the salvaged panel is eDP
- Chosen path: HDMI -> eDP-to-HDMI controller board -> salvaged panel
- Mechanical HDMI A/B switch retained as fallback for external display

add port layout and video output decisions
...
- Mechanical HDMI A/B switch for internal/external display toggle
- DisplayLink rejected: no ARM drivers exist
- 10-port layout split across 4 surfaces
- Port side: 4x USB-A, 1x USB-C data, 1x USB-C PD out
- Starboard: Ethernet, HDMI out, 3.5mm audio
- Bow: USB-C power input + fan exhaust
- Stern: handle, SD reader, Kensington lock
- Updated BOM with HDMI switch, panel-mount cables, SD reader
- Cost estimate now ~58
