Typography (deterministic, multi-locale)

Apply canonical typography via scripts/typo.js, a pinned-config wrapper around the typograf npm library plus deterministic post-rules for German and French gaps. Never rewrite quotes/dashes/spaces manually — always run the script so results are deterministic and idempotent.

Setup (first run only)

If scripts/node_modules is missing: cd <skill-dir>/scripts && npm install

Usage

# stdin → stdout; default locale chain ru,en-US
echo '"Привет" - мир' | node <skill-dir>/scripts/typo.js
# → «Привет» — мир

# Pick locale (first entry = primary): en-US, en-GB, de, fr, ru, uk, pl, …
node <skill-dir>/scripts/typo.js --locale=de file.md
node <skill-dir>/scripts/typo.js --locale=fr,en-US file.md

# Fix files in place / preview / CI check
node <skill-dir>/scripts/typo.js --in-place --locale=en-US file1.md file2.md
node <skill-dir>/scripts/typo.js --diff file.md
node <skill-dir>/scripts/typo.js --check src/**/*.md   # exit 1 + list if changes needed

# HTML entity output (&laquo; &nbsp; &mdash;) for HTML sources
node <skill-dir>/scripts/typo.js --html-entities file.html

# Conservative mode: quotes/dashes/spaces only (no date/money/number/symbol rewriting)
node <skill-dir>/scripts/typo.js --safe file.md

Per-locale behavior

ru — «ёлочки» (nested „лапки“), — with nbsp before, 5-6 → 5–6, nbsp after short prepositions and №, ... → …, т.е. → т. е.
en-US / en-GB — “curly quotes” with ‘nested’, spaced hyphen → em dash, …
de — „Gänsefüßchen“, Gedankenstrich: spaced hyphen → – (en dash, nbsp before)
fr — « guillemets » with narrow nbsp (U+202F) inside, tiret —, espace fine insécable before ! ? ; : (URLs like https:// are left untouched)

Hanging punctuation (optional, configurable)

Three routes, in order of preference by constraint:

No markup changes allowed → copy assets/hang-punctuation.js into the site and load it. It uses native CSS hanging-punctuation where supported (Safari) and falls back to DOM-only span wrapping elsewhere; source files stay untouched. Configure targets via window.HANG_PUNCT = { selector: '...' } before the script. If the page rewrites copy at runtime (a language toggle, a client router), call window.HangPunct.refresh() afterwards — the script only hangs what was in the DOM at load, and re-running it is safe.
Markup changes acceptable, ru text → run typo.js --optalign (HTML input only); it wraps hanging marks in classed <span>s. Include assets/optalign.css in the page. Note: --optalign output is not idempotent-safe with --check on already-spanned files; keep source pristine and treat it as a build step.
Zero effort baseline → add hanging-punctuation: first allow-end; to prose containers (currently Safari-only, harmless elsewhere).

Workflow notes

Choose --locale from the text's language; for mixed content, process each language's files separately.
Run only on prose/markdown/HTML text, never on source code. For i18n string files (e.g. src/i18n/strings/*.ts), pipe only string contents or verify with a build after --in-place.
For repo-wide fixes: --check first, show the user the file list, then --in-place.
The tool is idempotent; if a second pass ever changes output, report it as a bug rather than hand-fixing.
To adjust rules, edit makeTypograf() / postProcess() in scripts/typo.js so behavior stays pinned across sessions.
