Pull request overview
This PR adds a new documentation page covering Accessors — TypeGPU's schema-aware typed placeholders for GPU resources. It explains how accessors differ from slots when referencing GPU resources in reusable functions, and includes code examples with their corresponding WGSL output for all supported binding types.
Changes:
- New
accessors.mdxdocumentation page covering basic usage, supported binding types, deep/nested property access, mutable accessors, and a comparison table with slots and bind groups. - Navigation entry for the new Accessors page added to the sidebar in
astro.config.mjs, placed after "Slots".

| **Choose bind groups** when you need to swap resources at runtime without changing the compiled shader — the classic WebGPU pattern for per-frame or per-draw-call resource binding. | ||

| Accessors and slots operate at **compile time**: the WGSL output reflects which buffer or variable was bound. |

Actually, why is that? What stops the following from working?
const slot = tgpu.slot(5);
const fn = tgpu.fn([])(() => {
return slot.$;
});
console.log(fn());

Very nice, very cool, very comprehensive. Left one nit.
