Container: TinyTeX pinned to TeX Live 2025, replacing apt texlive - #341
Merged
Conversation
The texlive-latex-base/-recommended/-fonts-recommended + cm-super set added in #338 costs ~1.3 GB and still lacks type1cm.sty, so matplotlib's usetex path stays broken. Replace it with TinyTeX (~270 MB measured), pinned to TeX Live 2025 on both halves: bundle v2026.02, and tlmgr pointed at that year's frozen tlnet-final historic mirror. Packages are an explicit tlmgr list covering matplotlib's usetex preamble. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

#338 added
texlive-latex-base,-recommended,-fonts-recommendedandcm-superfrom apt: ~1.3 GB of image for a TeX that still lackstype1cm.sty, which matplotlib's usetex preamble loads, sotext.usetexremains unusable. This replaces that block with TinyTeX installed from the frozen TeX Live 2025tlnet-finalhistoric mirror (bundlev2026.02, the last built on TL2025), plus an explicittlmgrpackage list covering the usetex preamble: type1cm, cm-super, dvipng, underscore, ulem, amsmath, amsfonts, geometry, xcolor. Measured install size is ~270 MB, and both halves are pinned, so the layer resolves identically forever. Maintenance is once a year: bumpTINYTEX_VERSIONandTEXLIVE_YEARtogether; adding a LaTeX package is one line in thetlmgr installlist.ghostscriptstays (PDF/PS backends);dvipngnow comes from TeX Live. Verified outside Docker by running the same install into a scratch prefix and rendering a matplotlib-style usetex document throughlatex+dvipng.Supersedes #339.
