ℹ️ No critical issues — one test-coverage nit inline. The Acorn removal itself is complete and internally consistent.

Reviewed changes — initial review of commit 40eee14e ("only babel"). Removes Acorn as a supported tinyest-for-wgsl input and consolidates everything onto the Babel AST:

• Dependency changes — acorn dropped entirely; @babel/types promoted from devDependencies to dependencies (the public types now reference babel.Node, so downstream type resolution needs it as a real dep). Lockfile updated; the remaining lockfile acorn entries are transitive (rolldown, acorn-jsx, micromark, recma) and expected.
• Typing collapse — JsNode = babel.Node | acorn.AnyNode removed; transpileFn, transpileNode, extractFunctionParts, tryFindExternalChain, and Context.visitedNodes all narrow to babel.Node. The acorn-only PrivateIdentifier branch and Literal transpiler are gone (Babel emits the concrete literal node types, all still covered).
• Test simplification — dualTest / parseRollup helpers deleted; every case collapses to a single parseBabel run with snapshots unchanged.
• Object-literal key handling — new switch recognizes Identifier / StringLiteral / NumericLiteral / BigIntLiteral keys and throws on computed/other key types. String and numeric keys previously threw on the Babel path (only acorn's Literal was accepted), so this preserves the acorn-era capability and adds a dedicated test; computed identifier keys previously slipped through as literal names and now fail loudly — a strict improvement.

Verified locally: 18/18 package tests, 137/137 unplugin-typegpu tests (the only non-test consumer), clean tsc --noEmit, and repo-wide grep shows no leftover JsNode / acorn / dualTest references.
