/* Bitcoin blockspace investigation — "What filled Bitcoin's blocks".
   Generated by scripts/extract-bitcoin-blockspace.js from the design handoff —
   do not edit by hand; re-run the script instead. Scoped under .bitcoin-blockspace.
   Dark-only, like every other investigation: the handoff ships dark-only too,
   so there is no light token block to leave behind. */
