The web build could not reach any file: File > Open Session…, Import > Audio… and Import > MIDI… showed a text box for a path the browser can't read, and every save or export failed with «operation not supported on this platform», so work was lost on close. On the web now: - Open Session…, Import Audio… and Import MIDI… show the browser's file picker; files dropped on the page open (sessions) or import (audio, MIDI) by extension. Files travel as bytes; imports are one undo step each, like the import commands. - A session is saved as ONE file, a bundle `<name>.scraftz`: a zip (stored entries) holding the `.scraft` and its `Audio Files/` as 32-bit float WAV — the same layout as a session folder, since the browser has no folders. `io::open_session_bytes` opens a bundle or a bare `.scraft` (its audio is then reported missing). Bundles are hostile input: entry count and size are capped, and declared sizes are never read past. - Every single-file output (save, Save As Template, bounce, MIDI/score/text export, track presets) goes through `io::write_file`: a file natively, a download in the browser via a delivery hook (`io::set_deliver`) that only the web app installs. - In the browser Save As asks for the bundle's name (`<name>.scraftz`) instead of a folder path. Native builds keep writing files and session folders as before. Folder outputs (stems, clip exports) are still not available on the web. Pairs with #157 (Save on a never-saved session opens Save As), which the browser needs too: the web app always starts on the unsaved demo. New dependency: `zip` (MIT), default features off (stored entries only). Checked: engine tests for the bundle round trip (every sample identical), same-named sources, bare sessions and hostile bundles; `cargo xtask ci`. In Chromium on the packaged web build: ⌘⇧I picks and imports a WAV; WAV, MP3, FLAC, OGG, M4A, AIFF and MIDI import by drop; Save As → `Midnight Groove.scraftz` downloads with the imported audio inside; that bundle reopens in a fresh page with all tracks and no missing media, and saves again with the same content.
