`MimeType::parse_from_uri_with_fallback` compared the extension case-sensitively, so `app.JS` or `Style.CSS` fell through to the fallback (`text/html` for the `tauri://` and asset protocols), and `parse_with_fallback` only skipped `infer` for a lowercase `.svg`, so `Logo.SVG` was served as `text/html` or `text/xml`.

MimeType::parse_from_uri_with_fallbackmatched the extension case-sensitively, so a file likeapp.JSorStyle.CSSgot the fallback type, which istext/htmlfor thetauri://and asset protocols. The webview then refuses to runapp.JSas a module script.parse_with_fallbackalso only skippedinferfor a lowercase.svg, soLogo.SVGcame back astext/html, ortext/xmlif it starts with<?xml, and doesn't render in an<img>.This lowercases the extension before matching and makes the
.svgcheck case-insensitive. Added a test (should_ignore_extension_case) and a change file fortauri-utils.I used Claude Code to write this change.
