- SPI corruption: lower clock to 4 MHz (matches 7.3" prod) and push from internal SRAM in 8 KB chunks instead of streaming directly from a PSRAM scratch buffer. On the S3, Arduino's SPI DMA reads RAM directly — the CPU's cache can hold writes to PSRAM that the DMA never sees, painting the panel yellow/garbage. Internal-SRAM chunks are DMA-coherent. - LittleFS partition: switch the env to default_16MB.csv. The stock partition table for esp32-s3-devkitc-1 reserves ~1.5 MB for SPIFFS; three 960 KB setup-screen .bin files need ~2.9 MB + LittleFS metadata. - Setup screens: redesigned to match the 7.3" information density — yellow header band, two-column body with vertical divider, "Connect to WiFi" heading + 5 numbered steps + manual QR + side label on the left, Step 1 / Step 2 QRs on the right. - Orientation diagrams: PORTRAIT drawn upright (ribbon-bottom, up-arrow); LANDSCAPE drawn pre-rotated 90° CCW so it snaps to upright landscape when the user rotates the frame 90° CW (ribbon-bottom + left-arrow in portrait view → ribbon-left + up-arrow after rotation). "LANDSCAPE" label runs vertically up the long edge so it reads horizontally once the frame is mounted landscape. - New helper paste_rotated_text() — PIL's text() can't rotate, so render → rotate → paste-with-alpha. Used for the vertical LANDSCAPE label. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
