patriandClaude Opus 5.5 66f70c0cc1 Add 12-OBD-Speed: ELM327 speed over BLE on a GIF background 
- speed page: 120 px antialiased number (lv_font_conv) + 0-200 km/h arc
  gauge over ezgif-5-cb56986bc7.gif (embedded via board_build.embed_files)
- swipe-left menu: scan, OBD-like adapters first, tap to select; adapter
  remembered in NVS, auto-connect at boot and reconnect every 3 s
- ELM327 init ATZ/ATE0/ATL0/ATS0/ATH0/ATSP0/0100, then 010D polling
- shared ini: -DLV_LVGL_H_INCLUDE_SIMPLE for generated fonts

patriandClaude Opus 5.5 8a84b42a3b Add 11-BLE-Scanner: on-screen BLE scanner, inspector and ELM327 test 
- NimBLE-Arduino 2.5.1, BLE work in a background task on core 0
- LVGL 9 UI for the round screen: device list (OBD-like devices in green),
  tap to list services/characteristics, ELM test (ATZ/ATE0/ATI/ATRV/0100)
- results saved to LittleFS /ble_log.txt; serial d/c/s commands
- shared lv_conf: Montserrat 16 and 20 enabled

patriandClaude Opus 5.5 71d4bf7b58 display_gif_sd: load GIF from SD into PSRAM once, play from memory (9.8 -> 15.4 fps) 
Also enable a 16 KB LVGL stdio read cache (no measurable effect for the GIF).

patriandClaude Opus 5.5 55e27b6572 Port display_gif_sd and display_speed_wifi to LVGL 9.6 + shared library 
- both use shared/jc3636w518.ini, board library and perf monitor
- GIF decoded in the display color format, loop delay 1 ms,
  per-loop memory prints removed
- lv_conf: LVGL drive A: = SD card via LV_USE_FS_STDIO (/sdcard/)
- shared/README.md, CLAUDE.md and project README updated

patriandClaude Opus 5.5 6e7206b821 LVGL 9 tuning: CPU 86% -> 53% at full GIF speed (display_gif_embedded) 
- render in RGB565_SWAPPED (ST77916 byte order), no swap pass in flush;
  flush swaps only if the display format is plain RGB565 (runtime check,
  the previous #if compared enum values and was always true)
- QSPI clock 50 -> 80 MHz
- LV_ATTRIBUTE_FAST_MEM / FLUSH_READY in IRAM (lv_attr_jc3636w518.h)
- display_gif_embedded: GIF decoded in the display's color format (no alpha)
- tested without gain: LV_GIF_CACHE_DECODE_DATA (unused in 9.6), 120-row buffers

patriandClaude Opus 5.5 d6982ab7e7 Add shared JC3636W518 board library and PlatformIO config 
- shared/lib/JC3636W518: display/touch/backlight init with LVGL 9 glue
  (from scr_st77916.h), pin map, perf monitor (FPS/refresh/CPU)
- shared/include/lv_conf.h: LVGL 9.6 config for all projects
- shared/jc3636w518.ini: common platform/board/build settings
- display_gif_embedded uses it (23.2 fps, 86% CPU)
