+- **Host-agnostic Slug shader core** — Moved the Slug fill algorithm out of TSL into TypeGPU shader functions under `packages/text/src/internal/slug-shaders/core`, which import no renderer: the stable q-form solver, root-eligibility table, per-curve coverage and weight, band header and reference bit layout, screen-space scale, thickening factor, weighted blend, and vertex dilation are now shared by any WebGPU, WebGL, TypeGPU, or Three.js host. Both fill axes reach one curve evaluator and one quadratic solver because a vertical band is the transposed horizontal band with the opposite winding sense. The modules beside the core stay the Three.js host and keep the band loop, its sorted-reference terminator, the 2D grid addressing, and every texture read, since `@typegpu/three` has no texture bridge and grid addressing exists only because these resources are textures. Every crossing assigns its result to a named shader variable through one helper: the bridge resolves a core call by traversing the TSL nodes it reads, and TypeGPU's resolution context is a single stack, so a core node reachable through another core call's arguments resolves re-entrantly and fails a resolution-stack assertion. Added a device-free package test that compiles the staged material through both Three.js node builders and holds that invariant, the one-declaration-per-core-function property, and the absence of WGSL-only builtins from the GLSL output; hardware WebGPU and forced-WebGL2 probes cover source-outline fidelity, MTSDF/Slug comparison, and all seven presentation workloads. Made `typegpu`, `@typegpu/three`, and `@typegpu/gl` optional peer dependencies rather than bundled ones, since each keys its identity to a single instance exactly as Three.js and React do, and moved the reviewed package-size boundary to match: peer runtimes now sit outside the ceilings, leaving Slug's own emitted shader metadata — roughly 45,000 raw and 41,000 minified bytes of transpiled syntax trees — as the only growth, so its gzip and Brotli ceilings stay unchanged and shared with the other two rasters. Also refreshed the `@pmndrs/text` and `apps/benchmarks` source digests and several size baselines that the preceding tsdown/Rolldown emit commit left stale, plus one Wasm brotli growth allowance that was already exceeded against the committed report.
+
+- **Plugin-capable `@pmndrs/text` emit** — Replaced the package's direct `tsc` emit with tsdown and Rolldown in unbundle mode so shader source can pass a build plugin, presently `unplugin-typegpu/rolldown`, ahead of rewriting the Slug TSL shaders to TypeGPU. `dist` keeps one module per source file, declaration output, and the executable `pmndrs-text-bake` shebang; the seven JSON schema imports become sibling `dist` modules rather than copied files, so validators no longer rely on host import attributes. The bundler never becomes the type gate: `build` and `build:typescript` run the pinned compiler over the build project with `--noEmit` first, preserving the previous `noEmitOnError` behavior, and the new `dev:typescript` script re-emits on change without it. Package and integration suites, the compile-only type fixtures, and the benchmark application's typecheck all pass against the new output, and exact package-size entries were regenerated for the bundler's output.

 ## 2026-08-05
 
 - **Renderer portability orientation** — Reframed Three.js/TSL and React Three Fiber as the first integrations over portable text foundations, added a compact public-core-to-adapter graph, and marked the serialized renderer-agnostic core plan as WIP.
