Add drop/inner shadows, layer and background blur, and the three remaining
corner radii to generated style edits. Preserve the existing input order
and describe their authored groups independently of production metadata.
Check distinct inputs, main propagation, preserved overrides, corrupt
values and lost touched groups. Run component update, reset, detach and
exact undo/redo histories in common and the async frontend.
The input test fails six assertions before the addition. Focused common
checks pass 4 tests / 90 assertions; the six frontend histories pass
204 assertions. Full common JVM/JS, frontend, backend and exporter suites
and lint/format checks pass, including six 40-program properties at seed
712. F227's parity correction is covered separately. Golden data and
production behavior are unchanged.
Wider attribute/layout and source-copy generation, pending-work coverage
and the five fresh 5,000-program gates remain open.
