/**
 * Rare and crafted item name tables (`RarePrefix.txt` and `RareSuffix.txt`).
 *
 * In Diablo II, rare and crafted items derive their names from a combination of
 * one prefix (rare name 1) and one suffix (rare name 2) chosen from these tables.
 * Character save files (.d2s) store these two names as 8-bit unsigned integers
 * (0..255), which directly index the rows of `RarePrefix.txt` and `RareSuffix.txt`
 * in 0-based order.
 *
 * Unlike `MagicPrefix.txt` and `MagicSuffix.txt`, rare prefix and suffix tables
 * DO NOT provide stat modifiers; they only provide the generated names and their
 * item-type eligibility criteria (`itype1..7` and `etype1..4`).
 *
 * If all `itype1..7` fields are empty, the entry is a WILDCARD that can spawn on
 * any item type (for example, 'Warp' and 'Rift'). If any `etype1..4` match the item's
 * type, the entry is excluded.
