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).

Returns the center point <code>(x + w/2, y + h/2)</code> as a <code>Vector</code> — the anchor you want when placing a label or spawning at the middle of a box.
