Palette blueprints, searched nodes and moving blocks shared one engine but only the single current target line was visible, so there was no way to see where a dragged item could land. While a drag is active the overlay now outlines every valid dropzone with the engine's own predicates (accepts / acceptsInSlot, blueprint refusal, self-exclusion): containers in green, fitting slots in blue with a name tag, refused slots dimmed red with a name tag so they read as "exists but not for this". Tests: palette fit + slot-fallback, blueprint container/refused-slot, node fit/refuse on the same slot, move self-exclusion; typecheck clean. 🤖 Generated with Codebuff Co-Authored-By: Codebuff <noreply@codebuff.com>
