Browser SD files are persisted in OPFS (web/sdstore.js) and edited in the Files tab. At boot the browser builds a deterministic 64 MiB FAT32 image (web/fat32.js) with nested directories and VFAT long names, then mounts it as a raw block device, bypassing QEMU's broken populated-vvfat WASM coroutine path. Guest writes mutate only the ephemeral image. Exposes a hidden #frame-generation indicator that increments on every e-ink flush, so automation can wait on real display updates instead of fixed sleeps. Adds tests/ with a Makefile runner: 'make test' for JS + FAT32/mtools checks, 'make browser-test' for a headless-Firefox boot of the official CrossPoint 1.4.1 firmware that navigates to Test/example.txt. Bumps third_party/qemu to the SPI-SD/CMD13 fixes and updates README/ROADMAP/ISSUES for the new architecture.
