Function prewarm

brepjs — Public API

prewarm(): void
Trigger OCCT's deferred internal initialization by performing a trivial geometry operation. The first OCCT call in a WASM session incurs a ~400-900ms JIT penalty; calling prewarm() during idle time (e.g., after init() resolves but before user interaction) moves this cost off the critical path.

Safe to call multiple times — only the first call does work.

Returns void
Example
```
await init();
prewarm(); // fire-and-forget during idle time
```
