The localization layer was hardcoded to English and Japanese: an enum with two
variants, an `is_japanese()` gate compiled into the format macro, and one
catalog pair. Adding a language meant editing the menus, the settings row, the
checkmark logic, the format macro and the font stack — each in a different place.
A language is now one entry in `i18n::language_table!`: BCP-47 code, endonym,
ISO 15924 script and catalog. The Language menu, the settings row, the shortcut
sheet and the control channel are all built from that table, and `build.rs`
picks up `locales/<code>-formats.json` by name, so a further language is a table
entry plus two catalogs (docs/localization.md).
Simplified Chinese (`zh-hans`) ships as the second translation: `zh-hans.json`
(1019 entries, key-set and placeholder-identical to `ja.json`) and
`zh-hans-formats.json` (102 entries). Its glyphs come from craft-fonts' Noto
Sans CJK SC, whose `Hans` faces the UI now installs *before* the Japanese ones
for a Chinese reader, so shared Han characters keep the language's forms
(`fonts::cjk_fallback`); the export watermark accepts every CJK face.
`tr_format!` keeps its compile-time check. It formats the English source at the
call site — a runtime template cannot be handed to `format!` — and names those
values so a translation can place them by name (`{n}`) or position (`{_1}`).
Every translation is still checked by `format!`, so a translation with an
unknown placeholder fails the build. The Japanese catalog was rewritten from the
old `{:.0}` plural-discard trick to that by-name form; behaviour is unchanged.
Also: settings persist the BCP-47 code (never the Rust variant name),
`LIGHTCRAFT_LANGUAGE` accepts system-style tags (`zh_CN`, `ja_JP.UTF-8`),
`xtask parity` reads the second command table, and the glyph tests cover every
catalog character plus the interface symbols (`▸`/`▾` turned out to have no
glyph in any installed font and are gone from the Chinese text).
Chinese and Japanese both need `CRAFT_FONTS_DIR` as before; the web build still
embeds only the Japanese face (Noto Sans CJK SC alone would push the wasm past
Cloudflare's 25 MiB per-file cap), documented in docs/localization-zh-hans.md.

The Japanese fonts (BIZ UDPGothic Regular/Bold for the UI, BIZ UDMincho for text
watermarks; #110, #114) now come from storytold/craft-fonts instead of assets/fonts/.
- crates/engine/build.rs: the craft-fonts recipe. With CRAFT_FONTS_DIR set it embeds
the manifest's fonts as lightcraft_engine::CRAFT_FONTS (wasm32: BIZ UDPGothic Regular
only, for the web size budget); unset, CRAFT_FONTS is empty. Local files only, no
network; craft-fonts is not in any Cargo.toml.
- UI: theme::font_definitions adds the Japanese faces after Inter and egui's defaults
in every family (BIZ UDPGothic first, Bold first for semibold). About box lists the
embedded families.
- Watermarks: Inter, then the craft-fonts Japanese faces (Mincho first).
- Removed BIZUDPGothic-Regular/Bold.ttf, BIZUDMincho-Regular.ttf and their OFL files,
and their ATTRIBUTION rows; added an attribution row for craft-fonts as an optional
build input; NOTICE updated.
- Tests: Japanese glyph tests use CRAFT_FONTS and skip without it; new tests for
Japanese in the UI with craft-fonts and for the UI and watermarks without it.
- CI: the FreeBSD job builds/tests with craft-fonts. Releases check out craft-fonts at
a pinned commit, build with CRAFT_FONTS_DIR + CRAFT_FONTS_REQUIRED=1, and ship the
fonts' OFL licences (plus NOTICE) in every package.
- Docs: AGENTS.md, CLAUDE.md, README, docs/web.md, docs/localization-ja.md, ROADMAP,
parity.

Remove scripts/package-japanese-macos.py, the japanese-local feature and its
config/library/startup overrides, the settings.language migration, and the
local-build notes in the docs. Upstream library and config defaults (incl.
library::default_dir, which already honours LIGHTCRAFT_LIBRARY) are unchanged.
