Phase 1 of the fuller type-system proposal: two by-value spatial types that lower to packed integers (no heap, copy like scalars). - IVec2 — integer 2D vector, a pair of int packed into one i64, for tile and grid coordinates: make/zero/x/y/add/sub/scale/dot, the grid distance manhattan, equal, and to_vector (widen into the fixed-point Vector). - Rect — axis-aligned rectangle, four Q16.16 fixed components packed into one i128, for HUD boxes and hitboxes: make/x/y/w/h, the derived right/bottom/center, and the contains (point) / intersects (overlap) tests. Both are exact and deterministic, bit-identical on every platform. Vector and Color already cover phase 1's other 2D primitives. Wired end to end: emit_core llty (IVec2->i64, Rect->i128), emit_call dispatch, the FRAGS list + reseeded seed, a selfhost test (types2d), per-symbol docs + type pages + inventory, and the vocabulary/editor sync (header, JetBrains, TextMate, LSP).

Axis-aligned rectangles for HUD layout boxes, hitboxes, and camera regions. A Rect is four Q16.16 fixed components — position (x, y) (its top-left corner) and size (w, h) — packed into a single value that is copied by value and never allocates. It offers fast point-in-rect and rectangle-overlap tests. Every operation is deterministic fixed-point, bit-identical on every platform. Arguments are positional.
