Pure `nix fmt` output from the commit before this one — no hand edits. 203 files: 52 md, 42 tsx, 32 js, 32 css, 21 ts, 13 html, 8 json, 3 mjs. Reproduce with `nix develop -c nix fmt` on the parent commit; the result should be byte-identical to this tree. None of the 13 `.prettierignore` entries appears here — verified by intersecting the changed-file list against the ignore file, with a control proving the intersection finds a match when one exists.
