+# Accessibility
+
+Package Tools uses native headings, buttons, tables, details/summary trees,
+labels, status regions and dialogs. All workbench operations are keyboard
+reachable, focus indicators are visible, and state is not conveyed only by
+colour. Layout reflows to one column on narrow screens and follows the toolbox
+light, dark and system themes.
+
+The recursive package tree can be verbose for screen readers; path search and
+the tabular result view provide an alternative. Please report accessibility
+problems with browser and assistive-technology details.

+# Architecture
+
+The React workbench is a thin UI over four bounded layers:
+
+1. `src/archive` validates ZIP metadata, paths, sizes, compression ratios and
+   selected-entry extraction using zip.js without workers.
+2. `src/package/analyze.ts` selects at most 512 metadata files / 16 MiB,
+   determines a package adapter, parses static XML or bounded JSON, and builds
+   references and diagnostics.
+3. Tree and comparison modules create deterministic projections without
+   reading entry payloads.
+4. The preview path reopens the package and performs strict CRC/overlap checks
+   for one bounded entry. Markup is text-only; only browser-supported raster
+   image/audio/video blobs receive local object URLs.
+
+The UI lazy-loads the workbench beneath the shared toolbox shell. The app uses
+relative URLs so it works under nested portal paths, and a service worker caches
+same-origin resources after first use.

+
+Files remain in browser memory and are never uploaded. Package Tools performs
+no telemetry, DNS lookup, external relationship fetch, certificate lookup or
+signature validation. Export occurs only after an explicit button press.
+
+Limits in v0.1 include 512 MiB source and aggregate declared expansion, 20,000
+entries, 256 MiB per entry, 200:1 compression ratio, 2 MiB per metadata entry,
+16 MiB total inspected metadata, and 512 metadata files. UI rendering is capped
+at 5,000 tree/comparison rows while diagnostics cover the bounded inventory.
+
+External URLs are displayed as inert text. XML containing DTD or ENTITY
+declarations is rejected. SVG, HTML, JavaScript, PDF and executable content are
+never rendered from a package; raster image/audio/video preview is delegated to
+the browser through a local blob URL.
