3. Cache Storage with streaming progress — multi-hundred-MB downloads usable twice.
4. Indic Unicode-block transliteration — transliterate.js pre/post for non-Devanagari.
5. BPE / FLORES tokenization workaround — separate lang-tag and text tokenization.
6. Precision × provider UX — warn/auto-switch quant + WebGPU.
7. Precision-suffixed HF repos — one config key, many weight variants.
8. TTFT-aware tok/s — generation speed excludes first-token wait.
9. Dual static hosting — HF Space metadata + Pages workflow.
10. Zero-build footprint — five files, CDN deps, interview-friendly demo.
