What changed and why

FerroUI 0.1.7 makes the family ready for more languages, with English the one that ships (owner ruling on #112, 2026-10-19). No Dutch or German catalog is added.

• i18n: every string a component draws itself is a message of crates/ferrohealth-ui/locales/en/ferrohealth-ui.ftl (Project Fluent syntax), embedded at build time by fluent-templates 0.15.1 (static_loader! over locales/, verified on crates.io today; builds and lints on native ssr and on wasm32 hydrate and csr; no JavaScript). en is the reference: complete, the fallback of every lookup, and held complete by i18n::tests, which also checks any other catalog directory against the full message set, so a new language is a catalog file with no code change.
• The locale is chosen once per render: Locale (from a BCP 47 tag; negotiate over Accept-Language; negotiate_with over a console's catalog with its configured locale as the fallback), provide_locale at the root on both halves, locale() to read it, Locale::tag for <html lang>, Locale::lookup for a console's own catalog, Locale::with_catalog for a catalog the library does not ship. A page that provides none draws English.
• Proof: tests/it/locale.rs renders the pager and the confirmation dialog with a throwaway qaa catalog under tests/it/locales/ and sees the words change with no code change, while a message the catalog lacks falls back to English.
• scripts/checks/stray-literals.sh, a new CI job (stray-literals, in conclusion): fails on a string a reader sees in a component outside the catalog; scripts/checks/stray-literals.allow lists the literals that are no reader's text (key names, product names, SVG markup), each with its reason. A console runs the same script with a baseline that only shrinks.
• view::theme_switch::locale_switch: the language switch, each choice named in its own language and marked with lang (WCAG 2.2 SC 3.1.2).
• view::layout::keyed_field_row: a field row with an id (FerroFED's list rows hand-write the classes today).
• Rule and memory: .claude/rules/leptos-ui.md §0 and §13 and .claude/memory/ferroui.md: no user-visible component string outside the catalogs.
• Gallery: the overview's settings gain the language switch; the gallery's own pseudo-locale qps draws every library string accented and two fifths longer; <html lang> follows the cookie.

What a console must change: Theme::label, Density::label, Step::label, Severity::word and Variant::name return String instead of &'static str; button::label and copy_button accept a String as well. The English words and their markup are unchanged.

The bundle grows to 673607 bytes brotli (+53325 over 0.1.6): the Fluent parser, the CLDR plural rules and the catalog. The budget raise is its own pull request, #113, which merges first.

Left for the next release: the labels a console passes to components are still &'static str in most places, so a console cannot move its own strings until #114 lands.

Screens checked

• English: all 280 refreshed images diffed against main: every change is the version (Library v0.1.7 pill at row 10 of the wide shots, v0.1.7 in every footer) except the overview (the Language field, 1440 and 390, light and dark, in all four brands) and the skeleton shimmer's frame in tables-narrow. No other pixel moved.
• Pseudo-locale (FERROUI_PSEUDO=1, FerroBRIDGE brand, every page and sign-in card, 1440 and 390, light and dark, read): two defects found and fixed in this PR. The search box's Find button wrapped its word inside the button (it now keeps one line and the input gives way), and the pager's size choices broke with 100 alone on a new row (the choices now wrap as one group). What remains is graceful wrapping: the document pane's view choice and the theme switch wrap a segment to a second row at 390 px, and the pager's range sentence wraps over several lines, with no overflow and no sideways scroll.

Closes #112

Checklist

• Accessibility decisions cite WCAG 2.2, WAI-ARIA 1.2 or the Authoring Practices, not memory and not another library.
• Rust gates pass: cargo fmt --all --check, cargo clippy --workspace --all-targets -- -D warnings, the wasm32 clippy runs, cargo nextest run --workspace --locked, cargo doc with RUSTDOCFLAGS=-D warnings, and cargo deny check.
• A visible change refreshed the gallery screenshots, and I looked at every image it changed.
• A new or changed component was compared with the four consoles' versions (docs/qa/), and the best one on its merits was restyled to the library's tokens; the winner and the reason are stated below.
• Its interactive states (pointer, focus, open, each tone) are captured by tests/it/states.rs in every brand, light and dark.
• A release pull request says, per screen and per state, what was checked and what was fixed.
• Shell and workflow files are clean: shellcheck --severity=style, actionlint, zizmor --min-severity=low .github/.
• CHANGELOG.md has an [Unreleased] entry, if a console sees the change.
• No patient data in a fixture, test, gallery row or example.
• Every commit is signed.
• No AI or assistant attribution anywhere in the commits or this PR.
