// ---- The real Rec Room progression curve, ported from RecFlare -------------------------
// LEVEL_REQUIRED_XP[level] is the XP needed to LEAVE that level (indexed BY level). A
// player's stored XP is the progress INTO their current level - NOT a lifetime total -
// and every LEVEL_REQUIRED_XP[level] XP earned lifts them one level, carrying the
// remainder forward. This replaces the old made-up "1 + xp/1000" rule; the previous author
// left a note that the real curve should replace exactly that one method when it turned up.
//
// This is also what the client renders its progress bar against (see ConfigV2's
// LevelProgressionMaps, which now sends this same table), so client and server agree on
// what level an XP total is - the disagreement is what tripped the Level/XP anti-cheat
// ("obscured") check and dropped players to their dorm.
