- kerb_height ramp run now derives from --max-ramp-grade (default 8%), giving
1.63 m instead of the fixed 1.5 m (8.7%). Crossing route measures 3.4 cm at
0.25 m sampling.
- site_assembly pre-check: coverage is independent of --sample (it used to shrink
the route), and it now prints the grade and the s/offset location of the worst
step so a step can be located instead of guessed.
- Documents the remaining south s=198 / north s=251 strip discontinuity as a
finding on the 'audit collision gaps' item rather than claiming it fixed.
- Street + site rebuilt, site re-imported (7/7), DemoMap rebuilt; packaged
-qaselftest PASS.
