Collision layers and masks: a collider carries a layer and a mask of the layers it meets, and the pair only meets when both masks name the other's layer - the rule is one pure module (src/core/model/collisionLayers.ts) with layerBit, layersMeet and the names a project starts with, so the three places that have to agree read the same function: the editor run through CollisionSystem, the Solids sweep per pair and Rapier, where the mask becomes the collider's interaction groups; the project file gained collisionLayers: ["Default"] (default one layer, no formatVersion bump), the collider schema two new kinds - layer as a dropdown of the project's layers and layerMask as a menu of tickboxes that stays open while it is ticked (Menu.ts learned rows that do not close on a pick) - and the names are edited through "Collision layers..." in the toolbar's Project menu, not a Project tab, which is the decision I made myself because the question ran into the MCP timeout: the dialog (src/editor/CollisionLayersDialog.ts) holds up to 16 names, Add layer appends "Layer <n>" and Apply writes all of them as one undo step (SetCollisionLayersCommand); a mask read from a file goes through a check that refuses anything that is not a finite number, because Number(null) is 0 and a collidesWith: null would silently have meant "meets nothing"; 9 new e2e checks in module 8 cover the menu entry, the dialog, Add layer, Apply and its undo, both inspector rows, the tickbox menu, and the mover walking straight through the crate that 8c blocked on once their layers no longer meet, and 21 new unit tests cover the rule, the schema and the command (#152)

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)
