   `coco-cashu`), so don't chase those. The 1.9 MB entry is mostly framework + the
   English dictionary + shared UI; shrinking it means trimming those, not re-adding
   `manualChunks` (see the TDZ warning above).
+- **Repo weight (2026-10-28):** removed 1,295 tracked Gradle build files under
+  `packages/skatespots-nfc/android/build` (already gitignored; Gradle recreates
+  them), deleted unused `public/images/sticker-design.png`, recompressed the
+  large logo/cover/guide assets, and dropped the **threaded** ORT WASM variants
+  (`ort-wasm-threaded.wasm`, `ort-wasm-simd-threaded.wasm`,
+  `ort-wasm-threaded.worker.js`). The translation worker sets
+  `numThreads = 1`, so ORT selects `ort-wasm-simd.wasm` or the non-SIMD
+  `ort-wasm.wasm`; restore the threaded trio if threads are ever enabled.
+  Tracked tree is ~47 MB (from ~66 MB); the **.git history still contains old
+  blobs** — only a history rewrite (`git filter-repo`) would shrink clones, and
+  that would change every commit hash/tag, so it is deliberately not done.
 - **Load/relay performance (2026-10-28):** three structural costs were removed.
   ① `useAuthor` is now **batched** (module queue + one flush per tick): profiles
   are fetched with **one** main/fallback/community query per 100 authors instead
