#504 : test that the Backstage side menu edge is not a resize handle

The File side menu is a fixed 200-point panel, but egui left it resizable, so hovering its right edge drew a resize line and showed a resize cursor that did nothing. The test hovers the edge and checks the pointer is not a resize cursor. Without the fix it reports ResizeEast.
#2 : test that style gallery labels are truncated and hanging previews stay in view

 # WordCraft — instructions for agents

-WordCraft is a clean-room, open-source, Rust-native word processor targeting Microsoft Word parity — and going further on speed, openness and agent control. It runs natively on macOS, Windows, Linux and BSD, and on the web via WASM. Siblings with the same conventions: `../photocraft` (Photoshop), `../vectorcraft` (Illustrator), `../filmcraft` (Premiere), `../lightcraft` (Lightroom), `../pdfcraft` (Acrobat), `../effectcraft` (After Effects), `../designcraft` (InDesign).

It runs natively on macOS, Windows, Linux and BSD, and on the web via WASM.

Shared rules and learnings: [`storytold/craftrules`](https://github.com/storytold/craftrules) (`../../craftrules`) — read its `AGENTS.md`.

 ## Start every session here
 1. Read `plan/STATUS.md` (current milestone, next task), then the task in `plan/execution-plan.md` and the relevant `plan/architecture.md` section. `plan/` is gitignored (local only); if it's missing, start from `ROADMAP.md`, `docs/gaps.md` and `docs/roadmap.md` (Current focus).
 2. Follow the autonomous operation protocol (`plan/execution-plan.md` §5). Don't stop to ask unless a decision is genuinely the owner's (licensing, publishing, pushing to new remotes, secrets).

 ## Never crash
-People trust WordCraft with their writing; a crash loses their work. **This outranks feature work**: never ship a feature through a panic path, and fix a crash before building on top of it.

 - **Errors are `Result<T, E>`** through the crate's error type and `?`. An unfinished feature returns an error or is disabled; it never panics.
 - **Input-derived numbers are hostile** (files, commands, MCP/control params): `get()` instead of `[i]`, slice strings only at char boundaries, checked/saturating arithmetic, clamp sizes, cap allocations, bound recursion.

Without it the app builds, but English spelling falls back to an installed Hunspell English or the built-in Moby word list (with no American/British variant table) and pattern hyphenation is off (Bulgarian, Turkish and Russian still hyphenate by rule), so proofing tests need it.

- Don't add or change CI in a feature or fix PR. If the existing workflows can't build or test a change, link an existing craft-common-actions issue or PR, or open a new issue, or a PR only for a small fix that is safe for every app and does not increase CI time.
- Some workflow files here still run their own jobs. Don't add to them. Moving a job into craft-common-actions is its own task, never part of another PR, and the job stays here until a shared workflow runs it.

 # WordCraft — instructions for agents

-WordCraft is a clean-room, open-source, Rust-native word processor targeting Microsoft Word parity — and going further on speed, openness and agent control. It runs natively on macOS, Windows, Linux and BSD, and on the web via WASM. Siblings with the same conventions: `../photocraft` (Photoshop), `../vectorcraft` (Illustrator), `../filmcraft` (Premiere), `../lightcraft` (Lightroom), `../pdfcraft` (Acrobat), `../effectcraft` (After Effects), `../designcraft` (InDesign).
+WordCraft is a clean-room, open-source, Rust-native word processor targeting Microsoft Word parity — and going further on speed, openness and agent control. It runs natively on macOS, Windows, Linux and BSD, and on the web via WASM. Siblings with the same conventions: `../photocraft` (Photoshop), `../vectorcraft` (Illustrator), `../filmcraft` (Premiere), `../lightcraft` (Lightroom), `../pdfcraft` (Acrobat), `../effectcraft` (After Effects), `../designcraft` (InDesign). Shared rules and learnings: [`storytold/craftrules`](https://github.com/storytold/craftrules) (`../../craftrules`) — read its `AGENTS.md`.

 ## Start every session here
 1. Read `plan/STATUS.md` (current milestone, next task), then the task in `plan/execution-plan.md` and the relevant `plan/architecture.md` section. `plan/` is gitignored (local only); if it's missing, start from `ROADMAP.md`, `docs/gaps.md` and `docs/roadmap.md` (Current focus).
 2. Follow the autonomous operation protocol (`plan/execution-plan.md` §5). Don't stop to ask unless a decision is genuinely the owner's (licensing, publishing, pushing to new remotes, secrets).

 ## Never crash
-People trust WordCraft with their writing; a crash loses their work. **This outranks feature work**: never ship a feature through a panic path, and fix a crash before building on top of it.
+People trust WordCraft with their writing; a crash loses their work. **This outranks feature work**: never ship a feature through a panic path, and fix a crash before building on top of it. Standard: [`craftrules/standards/never-crash.md`](https://github.com/storytold/craftrules/blob/main/standards/never-crash.md).
 - **No panics in non-test code:** no `unwrap()`, `expect()`, `panic!`, `unreachable!`, `todo!`, `unimplemented!`; no `unsafe` (`unsafe_code = "forbid"`).
 - **Errors are `Result<T, E>`** through the crate's error type and `?`. An unfinished feature returns an error or is disabled; it never panics.
 - **Input-derived numbers are hostile** (files, commands, MCP/control params): `get()` instead of `[i]`, slice strings only at char boundaries, checked/saturating arithmetic, clamp sizes, cap allocations, bound recursion.
 - **Last-resort guard:** `Session::run` turns an escaped panic into an error and restores the document. It's a safety net, not a licence.
 - **Prove it:** every crash fix lands with a regression test. `crates/engine/src/tests.rs::hostile_params_never_panic` runs every command with junk params — keep it green.
- Production crate roots carry `#![deny(clippy::unwrap_used, clippy::expect_used, clippy::panic, clippy::unimplemented, clippy::todo, clippy::unreachable)]`; new crates start with it and add `[lints]` with `workspace = true` to their `Cargo.toml`. Tests may `unwrap` (`clippy.toml`).
+- Production crate roots carry `#![deny(clippy::unwrap_used, clippy::expect_used, clippy::panic, clippy::unimplemented, clippy::todo, clippy::unreachable)]`; new crates start with it. Tests may `unwrap` (`clippy.toml`).

 ## Assets: absolutely no Microsoft (or Adobe/Avid/Autodesk) iconography or images
 **This rule is non-negotiable.** Breaking it is the worst mistake you can make in this repo.
 - Never copy, trace, screenshot-crop or recreate icons, images, templates, themes, clip art, fonts, cursors, sounds or any other asset from Microsoft Word/Office or any Microsoft, Adobe, Avid or Autodesk product. Not even "temporarily".
 - Every asset must be **original** (drawn in code — prefer this: `crates/ui-egui/src/icons.rs`), **public domain / CC0**, **OSI open source**, or **Creative Commons that allows redistribution**, or licensed open source by a contributor who made it.
 - **Every asset file has a row in [`ATTRIBUTION.md`](ATTRIBUTION.md)** (author, source, licence). `cargo xtask assets` (part of `cargo xtask ci`) fails otherwise. Add the row in the same commit as the file.
- Fonts: new font files go to [`storytold/craft-fonts`](https://github.com/storytold/craft-fonts), never this repo; it's an optional build input (`CRAFT_FONTS_DIR`). Spelling word lists and hyphenation patterns live in [`storytold/craft-i18n`](https://github.com/storytold/craft-i18n) `language-data/`, never this repo; they are embedded from `CRAFT_I18N_DIR` (pinned by `craft-i18n.rev`, which CI checks out). Without it the app builds, but English spelling falls back to an installed Hunspell English or the built-in Moby word list (with no American/British variant table) and pattern hyphenation is off (Bulgarian, Turkish and Russian still hyphenate by rule), so proofing tests need it. Documents asking for proprietary fonts (Calibri, Aptos, Cambria…) are rendered with installed system fonts or metric-compatible open substitutes (`crates/fonts/src/word.rs`) — never bundle proprietary fonts.

When work lands, update the gap, the parity doc and the progress log, and bump each touched doc's status line and revision history.

-## CI workflows
- Workflows in `.github/workflows/` call the shared workflows in [`storytold/craft-common-actions`](https://github.com/storytold/craft-common-actions) at `@main`, with their inputs and secrets. No other jobs: if no shared workflow does what's needed, it doesn't go here.
- Don't add or change CI in a feature or fix PR. If the existing workflows can't build or test a change, link an existing craft-common-actions issue or PR, or open a new issue, or a PR only for a small fix that is safe for every app and does not increase CI time.
- Some workflow files here still run their own jobs. Don't add to them. Moving a job into craft-common-actions is its own task, never part of another PR, and the job stays here until a shared workflow runs it.

-# WordCraft
-
-A clean-room, Rust-native word processor. These are the words its interface, docs and code use for
-the same things.
-
-## Languages and proofing
-
-**Interface language**:
-The language of WordCraft's own menus, buttons and messages.
-_Avoid_: Display language, UI locale
-
-**Proofing language**:
-The language a piece of text is marked as, which decides how its spelling, grammar and hyphenation
-are checked. A language is told apart from another by its tag (language, script, region, variant),
-never by the name a list shows for it.
-_Avoid_: Text language, editing language, document language
-
-**Language pack**:
-A downloadable bundle of a language's spelling dictionary and hyphenation patterns.
-_Avoid_: Dictionary download, language data (that is the embedded data)
-
-**Language list**:
-The proofing languages offered in Set Proofing Language, Review › Language and the status bar's
-menu: the languages WordCraft names, plus those of every installed (and, in Set Proofing Language,
-every available) Language pack, each once.
-_Avoid_: Language menu (that is only one of the places it is shown)
-
-**Your languages**:
-The proofing languages Options › Language lists: each English variant in use (the default proofing
-language and any in the open document), every language with an installed
-Language pack, and every proofing language used in the open document.
-_Avoid_: Authoring languages, preferred languages
-
-**Default proofing language**:
-The proofing language new blank documents get, set with Set as default; without one, the interface
-language.
-_Avoid_: Preferred language
-
-**Proofing status**:
-Where a language's proofing comes from: built in, an installed Language pack, your own dictionary,
-a system dictionary, available to install, or not available.
-
-**Custom dictionary**:
-The words you added with Add to Dictionary, accepted in every language.
-_Avoid_: User dictionary (in the interface)
-
-**Dictionaries folder**:
-A folder of Hunspell dictionaries you supply, used before the system's (an installed Language pack
-comes after it).
-_Avoid_: Custom dictionaries

-# Security policy
-
-## Reporting a vulnerability
-
-Please report security problems privately through GitHub:
-**[Report a vulnerability](https://github.com/storytold/wordcraft/security/advisories/new)**
-(Security tab › Advisories › Report a vulnerability).
-
-Don't open a public issue or pull request for a vulnerability until a fix is released.
-
-Useful to include:
- the WordCraft version or commit, and the platform (macOS, Windows, Linux, BSD, web);
- what an attacker can do, and what they need (a crafted document, MCP or control-channel access, a local account…);
- steps or a sample file that reproduce it.
-
-We'll acknowledge the report, keep you updated while we work on a fix, and credit you in the advisory unless you'd rather not be named.
-
-## Supported versions
-
-Fixes go into `main` and ship in the next release. Older releases don't get backported fixes.
-
-## Scope
-
-In scope: anything that lets a document, file, command, MCP or control-channel request, or network response read or write files it shouldn't, run code, leak data, or crash WordCraft and lose the user's work.
-
-Crashes from hostile input count, because WordCraft treats every panic as a bug (see [Never crash](AGENTS.md)).

+# English spelling variants: American and British forms of the same word, for the English
+# dialects (#1281, #1045). Written by WordCraft contributors from general knowledge of English
+# spelling (MIT OR Apache-2.0); no other word list copied. See ATTRIBUTION.md.
+#
+# Each line: POLICY AMERICAN BRITISH
+# POLICY is three letters, for American English (en-US), Canadian English (en-CA) and the

+#   b  only the British form is right there
+#   *  both are right
+# Inflections (colours, centred, organising, organisation…) come from the rules in
+# crates/proof/src/en_variants.rs for -or/-our, -er/-re and -ize/-ise style pairs; other pairs
+# get only a plural, so list their other forms on lines of their own. When in doubt a form is
+# accepted: a false alarm is worse than a missed variant.
