- footer.tmpl: refactor to inject per-commit "View in 3D" links on the file history page, alongside the existing file view page button - ifc_url.go: add ')' to urlTerminators so bare ifc:// URLs followed by a closing parenthesis are correctly terminated - ifc_url_test.go: add tests for @ in query value, ) terminator, trailing period, and SERVICE_TOKEN presence/absence in preview URL - viewer.html: selector input placeholder and title attribute now document that the browser viewer only supports type-name union selectors - README: document viewer selector limitation vs full server-side behaviour Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
