-# Found 2026-07-20 (Phase 3, settings island increment 2): the assets/*/**
-# rule above only stops GIT from renormalizing the BUILT output - it does not
-# stop Vite from carrying forward whatever line endings the SOURCE
-# web_ui/src/islands/*/index.html happens to have on disk. That source file
-# is plain text, so `* text=auto` + a local core.autocrlf=true keep
-# re-materializing it as CRLF on checkout; Vite's HTML build step then bakes
-# those CRLFs into assets/<island>/index.html, which immediately "modifies"
-# against the LF-committed built file assets/*/** was meant to keep stable.
-# Same root cause as the assets/ rule, one file class further upstream -
-# opting the source index.html out of normalization too closes it for good
-# instead of needing a manual sed fix every time an island is rebuilt.
