backdrop-filter is fully implemented across two commits:
- marcoallegretti/stylo servo-weft f1ba496: enables backdrop-filter parsing
- marcoallegretti/servo servo-weft 8e7dc40: wires stacking context and display list
- CSS Grid is implemented via Taffy; backdrop-filter is the remaining unimplemented property
- Document the two-step implementation: stylo parsing enable + display list wiring
- Add Stylo fork section with patch template and step-by-step instructions
- Expand per-app process isolation section with clearer implementation detail
