The page hands one press/release edge to the UI per animation frame, but LVGL
reads the pointer every 30 ms. A press that lasted a single 16 ms frame (a
trackpad tap-to-click, or a synthetic click) was often never seen, so taps
landed at random. A press is now held for at least 70 ms before its release is
delivered.

pthreads for the UI's background tasks, LVGL + the UI loop on the browser main
thread (emscripten_set_main_loop), IDBFS at /data loaded before main() and
persisted after writes settle and on hide/pagehide; Reboot persists and
reloads. Page shell in the site's Night palette: Demo badge, Connect
placeholder, Reset demo data, Fullscreen; canvas scaled with aspect kept,
crisp at whole device pixels; pointer = finger, keyboard = CardKB codes.
serve.py and nginx-snippet.conf send COOP/COEP; without isolation the page
says so. Release -O2 (wasm brotli 1.14 MB), web-debug variant with -g.
