<div class="desc"><p>Allocates a raw buffer of <code>n</code> 32-bit words and returns a <code>words</code> value you can index with <code>buffer[i]</code> to read or write each word as an <code>int</code>. Use it when you want a flat, fixed-size numeric scratch array — a lookup table, a small ring buffer, or per-slot counters — without declaring a model. It is lower-level than a growable <code>[]int</code> slice: the size is chosen up front and there is no <code>push</code>. For byte-granular storage use <code>bytes</code> instead.</p></div>
