Nice restructure and changes! This looks great and maps cleanly onto the tutorial template. A few suggestions to revise the tutorial itself a bit before merging:

• Background: the claim about running "multiple LRCX operations in parallel" doesn't match the experiment (which sweeps a single LRCX over distances). Rephrase to reflect the actual comparison, for example:

  In this notebook, we adapt the protocol for IBM Quantum® hardware and benchmark its performance as a function of the control–target separation, comparing it against a unitary SWAP-based baseline.

• Large-scale Step 1: drop the misleading # Only works for distance larger than 2… comment — distance = 0 is a valid nearest-neighbor CX.
• Wrap Next steps bullets in <Admonition type="tip" title="Recommendations">…</Admonition> per the template, and use full URLs:

  <Admonition type="tip" title="Recommendations">
  
    - [Benchmark dynamic circuits with cut Bell pairs](https://quantum.cloud.ibm.com/docs/en/tutorials/edc-cut-bell-pair-benchmarking)
    - [Simulation of kicked Ising Hamiltonian with dynamic circuits](https://quantum.cloud.ibm.com/docs/en/tutorials/dc-hex-ising)
  </Admonition>

• Define MCM on first use, as "mid-circuit measurements (MCMs)".
• Drop the (i)–(v) sub-step numbering under Steps 1–2. The template's Step 1–4 headings already provide the scaffolding, and right now (i) is orphaned under Step 1 while (ii)–(v) live under Step 2.
