  <h2>Discarded Design Points</h2>
  <p class="section-description">
    Previous design concepts, analysis questions, and technical considerations that are 
    no longer relevant to the current top candidate design. Preserved for historical 
    reference and potential future revisitation.

        <strong>Reason for archiving:</strong> Current top candidate design does not 
        incorporate cable systems. Noise considerations for cables at speeds above 
        operational thresholds are no longer active design constraints.
