+The workbench uses semantic landmarks, headings and labelled native controls, supports keyboard operation, visible focus, reduced-width layouts, and system/light/dark themes through the Toolbox shell. Results do not rely on colour alone.

+# Architecture
+
+Text Tools is a static React/Vite application wrapped in the shared Toolbox shell. `text/pipeline.ts` defines an ordered, typed list of transformations. `applyPipeline` starts from the exact source, applies enabled steps one at a time, checks expansion after every step, and returns the last successful output with per-step before/after counts and warnings.
+
+Text encoding/decoding, line-ending conversion and Unicode-aware case primitives come from `@add-ideas/toolbox-helpers`. File decoding uses an explicit encoding and fatal-or-replacement choice; it does not guess a charset. Recipe JSON carries a schema/app identity, accepts at most 100 supported steps, discards supplied IDs and assigns local monotonic IDs.
+
+Version 0.1 operations are synchronous and bounded, so the app creates no worker and has no persistence or server API. Relative entry and asset URLs keep the build relocatable below a nested portal path.

+# Privacy and security
+
+Source text, imported files, recipes and results stay in page memory. There is no telemetry, analytics, account, persistence or runtime network path. Imported text is rendered as text/preformatted content, not executable HTML; HTML escaping produces a string and does not preview it as markup.
+
+Files are rejected above 16 MiB before reading. Decoded/pasted pipeline input is limited to 2,000,000 UTF-16 units, recipe text to 1,000,000 units/100 steps, and output to both 8× the original (with a small-input floor) and 32 MiB. These limits reduce accidental expansion but do not prove that output is safe for a downstream interpreter.
+
+Compatibility normalisation, case conversion, transliteration, whitespace/line transforms, column selection and narrow encodings can change or lose information. Locale sorting depends on the browser's `Intl.Collator`. The exact source, output, per-step counts and warnings remain visible so users can review those changes before copying or downloading.
