PlatformIO silently ignores data_dir inside [env:…] blocks (it warned
"Ignore unknown configuration option `data_dir`" on every run, but we
read past it). Without a recognized data_dir, uploadfs packed the entire
project data/ root into LittleFS, putting every file under
/waveshare73-v1/<file> instead of /<file>. The firmware looks at /, so
draw_from_lfs fell back to its solid-yellow epd_fill — a blank yellow
panel after a fresh uploadfs.
Moving the directive to the project-level [platformio] section makes
PlatformIO honor it. All envs currently target the V1 panel so a single
project-level data_dir is fine; when a second panel ships, swap via an
extra_scripts shim that picks the dir from \$PIOENV before uploadfs runs.
Reorganizes the tree so adding a new panel is purely additive — drop in a
new src/panels/{vendor}/v{N}/ folder and a new platformio.ini env block,
no surgery to existing files.
Layout:
src/ shared across all panels
src/panels/waveshare73/v1/ V1 driver, version, README
data/waveshare73-v1/ LittleFS payload at this panel's size
src/config.h still defines the panel-agnostic bits (NVS keys, color
palette, network, sync-fail border) but EPD_WIDTH / EPD_HEIGHT / pin
assignments now come from each env's -D flags. Strict #error guards in
production builds; native tests get the V1 defaults via UNIT_TEST.
build_src_filter per env picks the right driver:
waveshare73-v1 main + panels/waveshare73/v1/
test-display test_display + panels/waveshare73/v1/
sim-yellow sim_border + panels/waveshare73/v1/
sim-red sim_border + panels/waveshare73/v1/
native-test unchanged
When V2 hardware lands, the diff is a new env block, a new
src/panels/waveshare133/v1/epd_driver.cpp, and regenerated screens at
data/waveshare133-v1/. Existing V1 envs stay frozen — re-flashing old
units remains a one-liner.
scripts/gen_screens.py takes --panel to target the correct
data/{panel}/ subfolder; defaults to waveshare73-v1.
29/29 native tests pass. All four hardware envs build clean.

Two pio envs that build a tiny sketch reading /img.bin from LittleFS and
calling epd_draw_image_with_border with the chosen color. Lets us verify
the actual on-device pixel composition of the sync-fail (yellow) and
no-WiFi (red) borders without standing up a server failure or pulling
the WiFi cable.
Each sim sets NVS err_border=1 before halting, so flashing back to the
normal env afterwards exercises the 304 → clean repaint recovery path
end-to-end.

Three bugs fixed:
- NVS img_id now written before epd_init/draw; new draw_needed flag in NVS
survives power-loss mid-refresh so next boot re-draws from LittleFS instead
of showing stale content
- epd_sleep() now only called when display was initialized this cycle,
preventing a 60 s wait_busy() timeout on every 304 poll
- esp_task_wdt_reset() added to wait_busy() loop so the ~20 s 6-color
refresh no longer triggers the task watchdog
Also extracts normal_operation into operation.h template and adds
a native PlatformIO test suite (16 tests) covering the full response matrix.

State machine:
- Boot: check 5s reset-button hold → wipe NVS creds; load saved SSID/pass
- If no creds (or reset): enter_provisioning() — WiFi.softAP + DNS redirect + WebServer
- If creds: attempt_wifi(); on success → normal_operation(); on fail → enter_provisioning()
- normal_operation(): HTTPS GET /api/device/{mac}/image → stream to LittleFS → display;
204 = keep current stored image; 404 = red fill; server error = yellow fill;
deep sleep 15 min between polls
Provisioning flow:
- AP SSID: "PictureFrame-{last4hex}" broadcast as open network
- QR on e-ink: WIFI:S:PictureFrame-XXXX;T:nopass;; → phone auto-joins AP
- Captive portal: redirect all DNS to 192.168.4.1; serve minimal HTML form
(handles iOS /hotspot-detect.html and Android /generate_204 redirects)
- POST /connect: async — respond immediately, attempt WiFi in loop()
Success: save NVS, show Phase 2 setup QR (green bg) → 2min delay → normal_operation()
Failure: red fill → restart AP
EPD driver refactor:
- Extracted epd_init/sleep/fill/draw_qr/draw_image_from_file into epd.h + epd.cpp
- epd_draw_qr(): ricmoo/QRCode library; computes modules inline per pixel row
- epd_fill(): solid color in one pass (used for red=no-wifi, yellow=sync-fail)
- epd_draw_image_from_file(): streams LittleFS binary directly to display
Removed: convert_photo.py (pre-rendering moved to server-side Imagick), image.h (PROGMEM array)
Added: config.h, epd.h, epd.cpp; updated platformio.ini (QRCode lib, littlefs fs)

Move firmware files from repo root src/ into firmware/ to avoid
collision with Symfony's src/ PHP class directory. Add DDEV
config targeting PHP 8.4 / PostgreSQL 16 / nginx-fpm with
Imagick extension via docker-compose override.
