docs: resolve the hero façade width at 25.75 m

The OSM north edge measures 25.74 m, the sibling notes' own column spacing
(5 bays x 4.96 m + one column) gives 25.70 m, and the photo framing agrees.
The 29.6 m figure has no derivation and is dropped rather than averaged. The
neighbour outlines overlap by 0.1-0.3 m, so they are traced shared walls, not
approximate bubbles.
