Nine copies of escapeHtml (some escaping single-quotes + handling null,
others not), two byte-identical hashContent hashers, two saveContent
writers, two isZipMemberNode predicates, the ISO-date + YAML-quote helpers
duplicated across the workflow modals, three /.profile/access email
fetchers, and three byte-size formatters had all drifted across the browse
modules. Hoist a single browse-local window.app.modules.util (no new global;
concatenated right after init.js) and alias the call sites to it.
Reliability fix folded in: the YAML editor's saveContent skipped the
upload.ensureWritable() escalation that the markdown editor performs, so
saving a .yaml/.zddc file to a read-only-picked local folder failed where
markdown succeeded. Both now go through util.saveFile, which always
escalates — the shared writer makes the two editors impossible to drift
apart again.
Canonical escapeHtml is the strict superset (escapes & < > " ', null →
"") so it's a safe drop-in for every prior variant. fmtSize gains the GB
tier everywhere (history.js previously capped at MB). Also removes the dead
stage.js fetchSelfEmail (defined, never called).
Net −200 lines across the modules. No behavior change beyond the save fix;
all 6 browse Playwright specs pass.
