File-extension → icon map used to pick a file's icon when showIcons is enabled, e.g. { ".ts": "material-icon-theme:typescript" }. Keys are lowercase and may include or omit the leading dot. Values are resolved like icon() references: pack:name is used as-is, unprefixed names resolve via defaultIconPack, and none hides the icon for matching files.
