/**
 * URL-safe slug generator for ride names.
 *
 * Used as a secondary key on the `rides` table — the primary key is
 * (park_id, qt_ride_id) so renames don't lose history. The slug is just
 * for pretty URLs.
 *
 * Steps:
 *   1. NFD-normalize to split accented letters into base + combining mark
 *   2. Strip combining marks (diacritics, U+0300–U+036F)
 *   3. Strip trademark symbols
 *   4. Lowercase
 *   5. Replace any non-alphanumeric run with a single hyphen
 *   6. Trim leading/trailing hyphens
 *
 * Examples:
 *   "X²"                         → "x"
 *   "Lex Luthor: Drop of Doom"   → "lex-luthor-drop-of-doom"
 *   "Catwoman's Whip"            → "catwoman-s-whip"
 *   "Façade"                     → "facade"
 *   "Batman™ The Ride"           → "batman-the-ride"
