Web files: designs live in the browser (OPFS), files come in by picker or drop and go out as downloads
- solvecraft_io::vfs: the engine's file access (disk natively; in the browser an in-memory set of files the host loads and stores). File commands and write_atomic go through it. - Web host (apps/solvecraft-web/src/files.rs): stored designs are read from OPFS at start (storage.persist() asked for) and written back when a command writes one; Save/Save As keep designs in the browser, exports (STEP, STL, 3MF, OBJ, ...) download as files. - File > Open shows "Files in this browser": open, insert, rename, download, delete, plus open or insert from the computer (showOpenFilePicker where there is one, an <input type=file> otherwise). Files dropped on the page are inserted or opened. - Unsaved work is autosaved to OPFS and offered again after a reload or crash. - Start page recents come from the stored designs, with thumbnails. In the browser the samples are built when opened (a picture blocks the page there, and a kernel panic can't be caught). - Pages without OPFS (http on a network address, old browsers) keep designs in local storage.
