Reviewed the changes to how placeholder metrics resolve modifiers (now via the shared resolve_caret_modifiers instead of duplicating logic off NodeView::effective()). Verified that Alignment still resolves correctly through the new caret-based path (non-inheritable, resolved via ancestor paragraph match) and that the refactor compiles cleanly (deref coercions, Copy types). No bugs, logic errors, or security issues found.
