Daily Reward Roller

A weighted random reward device: press a button to roll a reward from a weighted table, with a per-player streak that gently improves the odds.

  # A self-contained reward device. When a player triggers it (e.g. opens a chest
  # via a button), it rolls a RANDOM reward from a weighted table and grants it by
  # enabling the matching item spawner. A simple per-session "streak" counter
  # nudges the odds toward better rewards the more a player keeps interacting.
  #
  # Teaches: parallel @editable arrays as a weighted table, weighted random
  # selection with GetRandomInt, a per-player counter in a map keyed by agent, and
  # clean fallback handling. Persistence is intentionally left out to keep this a
  # focused, drop-in sample (swap the streak map for saved data when you need it).
