Four related fixes to stop buffering files in page memory and stop hammering layout from the selection paths: - Inline viewer media: video/audio fetched the ENTIRE file into a blob before the first frame (a 2 GB video = 2 GB of tab heap, no progressive playback, no seek). The <video>/<audio> src now points straight at the same-origin API URL — cookies travel automatically and the browser streams with native Range requests, exactly like the music player already did. - Downloads (file, folder ZIP, batch ZIP, viewer button): the fetch → blob → objectURL pattern materialized the whole payload in RAM before the save dialog appeared (a 10 GB batch ZIP risked crashing the tab) with no download progress UI. New shared utils/download.js hands the URL to the browser, which streams to disk with its own progress UI. Batch download uses the existing GET endpoint (same URL contract as the drag-out DownloadURL, now shared via buildBatchDownloadUrl); selections whose id list cannot fit in a URL keep the buffered POST fallback. Trade-off: failed downloads now surface in the browser's download shelf instead of an in-app toast. - Rubber-band lasso: every mousemove (>100/s) walked all cards interleaving getBoundingClientRect() reads with class writes — up to N forced reflows per event, freezing the frame rate on folders with thousands of loaded rows. Card rects (+ item info) are now snapshot once per drag (rebuilt on scroll), and a single rAF pass per frame compares against the cached geometry, touching only cards whose selection state changed. - batchToolbar: getSelection() rebuilt the selection by scanning every .file-item in the document (the TODO admitted it); it now reads the _selected Map that every selection path already keeps in sync. clear() scopes its DOM sweep to #files-list (the only container the toolbar manages) instead of the whole document. https://claude.ai/code/session_01Dp3oWon5GBMVn4j3QXZdgx

/**

* OxiCloud — Batch Toolbar Module
|
|
*
|
|
* Manages the floating selection bar that appears when items are selected,
|
|
* and executes batch operations (delete, move, download, favorites).
|
|
*
|
|
* Selection state (_selected, handleToggleItem, selectAll, …) is kept here

|
* Once ui.js is migrated to ResourceListComponent (plan step B5), all

* selection mechanics will live in the component and this module will
|
|
* shrink to only the toolbar UI and batch-operation API calls.
