The simulator now shows the full source image with a draggable crop
window overlay. Drag the frame over the photo to position the crop —
dimmed regions show what gets cut. The dithered e-paper preview renders
live in the side panel.
Mode toggle: "Fill" (zoom with draggable pan) vs "Fit" (letterbox).
Save persists per-image settings used when the ESP32 fetches the photo.

- E-paper display simulator: Python port of the C++ Floyd-Steinberg
dithering (same palette, same coefficients) with side-by-side preview
in the web UI. Interactive pan/zoom controls with live re-rendering.
- Frame orientation: landscape / portrait_cw / portrait_ccw setting
controls logical display dimensions (800x480 vs 480x800). Images are
rotated to match the physical buffer after processing.
- Display modes: zoom (cover+crop) and letterbox (fit with padding),
configurable globally and per-image. Zoom mode supports pan_x/pan_y
(0.0-1.0) to control crop position.
- Settings persistence: frame settings, per-image settings, and frame
state stored as JSON, surviving restarts.

Adopts the weather-display pattern: .env file parsed by tools/load_env.py
and injected as -D compiler flags. WIFI_NETWORKS uses "SSID:password" format.
ESP32 now sends a heartbeat POST after each display update so the server
can track frame status for the HA integration.

ESP32-S3 firmware (PlatformIO) that fetches JPEGs from a photo server,
decodes on-device with PSRAM, Floyd-Steinberg dithers to the Spectra 6
6-color palette, and displays on a 7.3" GDEP073E01 e-paper panel.
Deep sleeps 1 hour between updates.
Photo server (Python/Flask) with web UI for photo management, Traefik
routing at photos.haunt.house with Google OAuth, and Home Assistant
REST sensor integration.
