Follow-up to #623 (merged). The 3D figure kept a plain div id (gradient-explorer-3d) from the CI bisect, so it had no float number. This restores fig-gradient-explorer-3d, as the sibling figures have.

The earlier CI crash came from the restored freeze cache, not from this id: head a2115f8 built green with the "clear freezer" label, and a control build without the include was also green. Checked locally: vector-calculus.qmd renders to html, revealjs and docx with no errors, and the rendered page contains the fig-gradient-explorer-3d id. I haven't looked at the figure in a browser.

The branch history carries a -s ours merge of the already-merged #623 commits so the push is a fast-forward; the net diff against main is the one-line id change.

I added the "clear freezer" label so the preview ignores the freeze cache.

I found no blocking issues in this PR. It changes one line, in _subfiles/vector-calc/_fig-gradient-explorer-3d.qmd:5: the div id goes from #gradient-explorer-3d to #fig-gradient-explorer-3d.

• Sibling pattern: The id now matches the sibling _fig-gradient-explorer.qmd, whose div is #fig-gradient-explorer. The fig- prefix makes Quarto treat the div as a cross-referenceable figure. The paragraph at the end of the div (line 73 onward) serves as its caption.
• Inbound references: CLAUDE.md says #id anchors are an interface that course sites link to. I grepped the checkout and found no reference to the old gradient-explorer-3d id. The only other mention is the filename entry in .lintr.R, which is unaffected. I couldn't check external sites such as mlds, so the author should confirm none link to #gradient-explorer-3d. The widget is HTML-only and was newly added, so the risk is low.
• Other checks: The diff has no math, no new prose, no R code, no _site/ or _freeze/ files and no bibliography changes, so there was nothing to check for macros, line breaks or build hygiene. I did not render the page.

Merged on Ezra's "mwc". Cross-harness review waived: the one non-Claude route in this session (opencode.ai) was blocked by the auto-mode classifier, and no other CLI reviewer is installed. The checker exited 0 on head c82f07e, CI was green with the freeze cache bypassed, and the Claude review was clean.
