How this page stays fast

The list is rendered from /public/assets/pt/v1/index.json (small, cacheable).
Per-refrigerant PT curves remain separate files under /assets/pt/v1/refrigerants/ and load on demand in the PT tool.
This route supports server-side filtering via query params (indexable, no JS required).
