Per the freeze protocol: only new files + root import touched. I haven't added LiContour to the root yet — do it at the end (or now? The root import is allowed. Let me add the import now so the full build covers it... but then each sub-stage build includes the WIP file. That's fine as long as it's green. Actually — add the import at the END of ii′-4 to avoid breaking the full build if a later sub-stage has issues mid-way. For now the single-file check covers it. Hmm — but for the commit to be \"green\", the file must compile — it does (single-file). Let me add the root import right away actually: it keeps `lake build` honest at every commit, and I only commit when green. I'll add it now.)\n\nWait — ordering: LiContour imports LiSides and LiSkeleton. Root lists imports alphabetically-ish: LiSkeleton, LiBasePoints, LiResidue, LiPrincipal, LiSides, LiSwaps, LiZetaCoeff, LiDigamma, LiArchimedean, ... Add `import NguyenRH1.LiContour` after LiArchimedean. Also update the root module doc Contents list.\n\nThen commit 4a.
