947a6b1 (#141), 6a31f5e, 4f55f85 and ae3aa7d gives the same 85-148 ms, the cost has been there since outlined cells arrived with #141; new pure functions shapeBounds/grownBounds/boundsMeet in collider.ts and cellsWithin/cellsMeet in tilemapCollision.ts, 11 new unit tests in tests/core/broadphase.test.ts (the rectangles of all four shapes including a rotated box measuring its diagonal reach, touching counts as meeting, cellsWithin straight and turned by 90 degrees, a map handing out 400 cells without a range and under 10 with one, an 800 unit move from far away still stopping at the first cell, a rotated map blocking where its one painted cell was turned to, a ray across the whole map, and the editor run seeing a collider on a far cell), and four counter-checks hold: dropping the cell filter fails the counting test, padding without the move length fails 4 move tests, ignoring the rotation in cellsWithin fails 3, and a wrong range in the detection fails the touching test; one blunt test on the way - the first rotated map was painted on every cell, where even a wrongly computed cell range blocks and the counter-check stayed green, so exactly one cell is painted now and the test measures where it turned to; no e2e check and the check sum stays 1157, because a timing check in the browser would flutter under CI load while modules 40 and 42 cover the correctness anyway, the speed evidence being the node benchmark (#184)

Moving against a tilemap whose cells block with an outline no longer costs more than a whole frame: an outlined cell is its own polygon, split into convex parts, so a map that is a handful of merged rectangles when built from plain solid tiles is hundreds of solids under one entity - and Move brought every one of them into world coordinates and tested it exactly, including the ones on the far side of the map, which measured 148 ms per Move call on a 20x20 map with 16-corner outlines (34 ms at 8 corners, 0.4 ms with plain solid tiles), matching the report that standing still holds 60 fps while anything that moves stutters; the fix is a broad phase in two stages that decides nothing and only leaves out what cannot be reached - a move never ends further from its start than it is long, because sliding always shortens the rest, so every collider of the mover gets a rectangle grown by the move length and an obstacle whose rectangle does not meet it is never tested, a ray taking the rectangle around itself, and that rectangle is carried back into the map's own units with invert(m) and turned into cell coordinates (cellsWithin), a rotated map through its own axes, so a far cell is not brought into world form in the first place - solidShapesOf was O(cells) per call, which was the second cost block and the reason the 60x60 case still grew; CollisionSystem.overlaps takes the same range, so the editor run asks a map only for the cells within reach of the other side each frame, two maps narrowing nothing, and a Move obstacle now falls away at build time when its layer does not meet the mover's (#152) instead of inside the loop; the measurements after: 148 -> 0.26 ms, 34 -> 0.27 ms, 60x60 20 -> 3.5 ms, plain tiles unchanged; this is no regression of the recent commits - the same benchmark in worktrees against

The topbar is icons only: the leading Project dropdown, the Scene picker and the labelled Play/Pause buttons are gone and in their place stand five icon buttons - menu, undo, redo on the left, play and pause in the middle - while Notice, the save state, fps and the Account menu keep the right side; the Play button swaps its icon for a stop square while the project runs and Pause swaps for a second play sign while it is held (Button.setIcon()), and iconSpace() drops the gap between icon and label when a button has no label, which is what kept a 24 px icon button 3 px off its own centre; the menu carries New project, Open project..., a separator and Project settings..., where the picker (src/editor/OpenProjectDialog.ts) preselects the open project and marks it "open", opens on a double click and puts Delete on the left of Cancel and Open - it closes itself before it asks whether to delete, because two modals on top of each other would have left the question standing over a list it no longer speaks about - and the settings dialog (src/editor/ProjectSettingsDialog.ts) holds the name, the "Play starts" switch (Start scene / Active scene, a preference of this browser and so no command) and the collision layers from #152, which retires CollisionLayersDialog.ts and the "Collision layers..." entry; what Apply actually writes is the pure function settingsChanges(), so renaming and the layers are each their own undo step and each drop out when nothing differs; the Scene dropdown falls away without replacement, the active scene is switched by double clicking it in the Assets panel, which is the way that was there anyway; new module 46 runs last with 9 checks (no label left in the bar, the run buttons in edit mode, the four menu entries, the picker with the open project preselected, Cancel leaving the project standing, the settings dialog on the state of the project, renaming with undo and redo through the icon buttons) and it neither opens nor deletes a project, because that would pull the project out from under every earlier module; modules 8, 18 and 35 and the harness follow the new bar, 6 unit tests cover settingsChanges and 3 the icons (#183)

Asset panel grouped by kind with icons: assets are listed under a header per kind (Sprites, Behaviors, ...) with the count on the right, empty groups are not shown, every group starts folded when a project is opened, a click on the header folds and unfolds it, selecting an asset elsewhere unfolds its group and folding the group of the selected asset clears the selection; every asset kind has an SVG icon in src/editor/panels/icons/ drawn before the name, the pure rule for grouping and sorting lives in assetGroups.ts; the same icons replace the kind word in document tabs and the overflow menu (a list icon for the List tab, which also fixes the close x lying over the end of the active tab's text), stand before every entry of the + menu (Button got an icon option) and on the right of scene object rows instead of the type name; the colour swatch next to sprite names is gone from both panels; the SVG loader moved to src/ui/svg.ts for both icon sets; test hook assetRow unfolds the group and scrolls to the row, assetRowShown only reads, new hook menuIcons; e2e 4g and 4h, 14 and 44a check the icons (#176)
The new node "Raycast all" answers with every collider along the ray instead of only the nearest one: it carries the same inputs and settings as Raycast (Ignore owner, Hit triggers, Layers from #158) plus "max hits" where 0 means all, and it hands back parallel lists sorted by distance - objects, colliders, points x/y, normals x/y, distances - next to count, so index i of every list speaks about the same hit; a collider counts once no matter how many convex parts its shape is built from, while a tilemap counts per cell it is hit in, and the filter sits in Solids.raycastAll like the one of #158, the one path the editor run and Play both take, so all 12 new unit tests run through describe.each against both systems; the node needed the value system to learn something it could not do - a graph list carried numbers, text, booleans and bundles but no object handles, asList turned an object into its name, so objects/colliders would have been lists of names, which loses the object when two carry the same name, and collider children usually do; Value now knows a travelling list that may hold handles and "Item at" gives such an item out as an object, ready for Destroy, Apply force or Name of, while the single door into a stored file - writeTyped/asTypeOf - runs the list through the new storedList() so every object becomes its name again and nothing living reaches a project file, which is its own unit test over JSON.stringify; three list nodes follow the handles: "Index of" compares objects by identity because a name is not the object of that name, "Set item" and "Fill" write an object as an object, and "Join text" prints the names instead of the innards; this decision was mine to make because the question ran into the MCP timeout - the alternative was a list of names plus "Object by name", which is the smaller change but lossy; 4 new e2e checks in the new block 43e (shield and floor in one go reading 2 and "145, 280", the second object answering to its name, which only a real object in a list can do, "max hits" 1 stopping at the nearest, and the node showing the row) and 18 new unit tests, 12 in raycast.test.ts, 4 on the value system and 2 in the node catalog; two counter-checks hold: not counting tilemap cells one by one drops 2 unit tests, and answering with the nearest hit only drops module 43 with 2 FAILs; one finding on the way - the node read "maxHits" while every other input carries a spoken label, because int() took the key as its label, so it has a third parameter now, and the e2e check caught that, no unit test did (#157)
