Exporting selection to format with extension

Error message

Exporting selection to format with extension "{ext}" is not supported.

What it means

Validation error in get_selection_export_format: the user-supplied --export-format string does not match any supported selection export extension (svg, png, jpg, jpeg), so no SelectionExportFormat variant can be built and selection export cannot proceed.

Solutions

1. Re-run with a supported --export-format value: svg, png, jpg, or jpeg.
2. Check the format string for typos or casing; matching is exact and case-sensitive.

When it happens

Trigger: Thrown at crates/rnote-cli/src/export.rs:409 when the library encounters an invalid state.
