# champollion.dev/queue — community sweep-queue viewer.

#   curl -fsSL champollion.dev/queue | bash
#
# What it does (and nothing more):
#   1. Fetches champollion.dev/queue.json (the public sweep queue).
#   2. Pretty-prints the top open items with their exact `mt-eval run`
#      commands, ready to copy-paste.
#
# It NEVER executes a benchmark, never spends your tokens, never writes
# files. Display only. Run the printed commands yourself when ready.
#
# Options (pass after `bash -s --`):
#   --top N        show N items (default 10)
#   --json         dump raw queue.json to stdout
#   QUEUE_URL=...  override the queue location (env var)
