Broken rear leaf spring

A broken rear leaf spring is visible during the initial walk-around — consistent with the rear-impact account relayed by other Tremor owners. This becomes the entry point into the bigger rear suspension decision covered in the build list: whether to simply replace it like-for-like or use the repair as the moment to move to a progressive-rate spring pack instead.

Philosophy note: the goal is to avoid replacing the same part twice. A broken spring gets repaired once, correctly, accounting for the eventual towing and ride-quality goals rather than just restoring to stock.
