test(html): render csv and zip in the output tests

[andiwand]

🤖 Generated with Claude Code

Fifth of the csv stack. Based on #669 — the value types change what a cell renders as, so the reference output has to be generated with them in.

Both csv and zip sat behind a TODO enable in html_output_test.cpp, and for different reasons.

Csv

Skipped because it rendered as a line list, which was not worth pinning. It renders as a table since #668, so the skip has outlived its reason. The reference output gains document.html and sheet0.html — the one-sheet spreadsheet the generic renderer walks, capped at the suite's 4000 rows.

Until now the only thing pinned for a csv was meta.json, which is written before the skip. That is also why the documentType line reverted in #668 needed an output-repo commit of its own; it is folded into the same one here.

Zip

Skipped because there was nothing to render. get_test_files walks the input directory and maps by extension, and the public input set had no archive at all — so the skip was dead code.

zip/small.zip is new input and deliberately tiny: 271 bytes, two text files.

  Length      Date    Time    Name
---------  ---------- -----   ----
       14  01-01-2026 00:00   hello.txt
       33  01-01-2026 00:00   nested/note.txt

The reason for the size is html/filesystem.cpp: an archive renders as a file listing and every entry becomes a data:application/octet-stream;base64,… download link (html/common.cpp:96). A real-world archive would carry its whole content into the reference output, base64-inflated. At this size the whole listing is 854 bytes and reads in a diff:

<a href="data:application/octet-stream;base64,SGVsbG8sIHdvcmxkIQo=" download="hello.txt">

Json stays skipped — no renderer of its own yet.

Data repositories

Both pins move, and both commits are on main of their repo:

• input OpenDocument.test → d7c093d a small zip to render
• reference output OpenDocument.test.output → e9aa12f zip: render the file listing, on top of 33300e7 csv: render as a table

Verification

Full suite, 815 passed / 8 skipped. diff -rq of the generated tree against the reference is empty for both repos — the only files that moved are the three the two new renders produce.
