Inline handlers built as onclick="fn('${esc(id)}')" were injectable:
esc() turns ' into ', which the browser decodes back to ' before
the JS runs, so an id like x');alert(1);// broke out of the string.
Ids can come from a restored backup file or a synced catalog. Add
SunSafe.jsArg (JSON.stringify + HTML escape) and use it in all 23
handlers in app-runtime.js and index.html. Verified in a browser: a
payload id is passed through as a plain string and nothing executes.
Also replace the Settings version label that still showed
v17.6.0 · 2026.09.07, and bump the cache-busting version of the two
changed scripts (sun-safe.js, app-runtime.js).
