/**
 * Position quantization helpers.
 *
 * A position component is a signed float in some bounded world range (e.g. ±256m
 * for a typical action game level). We pick a number of quanta per unit
 * (e.g. 4096 quanta/m for centimetre-precision-ish accuracy) which together with
 * the range determines the bit count.
 *
 * `bit_count = ceil(log2(2 * range * quanta_per_unit))`
 *
 * For the Glenn Fiedler State Synchronization defaults (range = 256m, 4096 quanta/m):
 * 2 * 256 * 4096 = 2097152 = 2^21 → 21 bits per component, 63 bits per vec3.
 *
 * (We measure "number of quanta intervals" rather than "number of distinct values",
 * which gives one fewer bit at exactly-power-of-two configurations and matches
 * the conventions used in the netcode literature.)
