No active review issues are reported for the CSS source-map fallback change.

No open issues 🎉

What changed in this PR

Preserves CSS source indices in bundled source maps when an input source map cannot be read, allowing the printer to use the original CSS as a fallback.

Changes:

• Registers the CSS source based on whether the input map can be read, rather than its URL prefix.
• Adds regression coverage for an external map URL and an invalid inline map, verifying fallback mappings, source paths, and source content.

File	Description
tests/​test_bundler_source_map.rs	Tests fallback source registration for unreadable input maps.
src/​bundler.rs	Checks input-map readability before omitting the CSS source.
