Vendored Hunspell en.aff/en.dic into web/public/dictionaries/en/ (served as a
static asset + embedded in the binary, kept out of the JS bundle). dictionary-en
moved to a devDep — only used to source the files.
- useSpellChecker (App-level, loads once/session): fetches the dict, builds an
nspell instance, replays a localStorage personal word list; addWord persists
and bumps a version so consumers re-decorate. Ambient types in
src/types/nspell.d.ts (the package ships none).
- SpellCheck Tiptap extension: misspellings as ProseMirror decorations (no
stored marks), recomputed on edit / caret move / checker swap. Latin-only
tokenizer so CJK is never flagged; skips short tokens + all-caps acronyms;
exempts the caret word to avoid mid-typing jitter. Reuses mapOffset (now
exported from SuggestionHighlight); wordAt resolves the exact span on click.
- MisspellCard: soft rose wavy underline, bilingual popover with up to 5 nspell
corrections (click to replace) + add-to-dictionary. Closes on outside-pointer,
edit, or doc switch.
Chinese spell check intentionally omitted — nspell is dictionary-based and
English-only; Chinese typos (homophone 别字) need an LLM, out of v1 scope.
tsc/vite/go build+vet clean; live server serves both dict files; nspell
behavior smoke-tested.
