mirrored_rail_axis_separation
2 x 7'-0" (HALF PLAN about CENTER LINE OF ENTRANCE)14 ft
This is a local symmetric separation between mirrored rail axes, not a world-coordinate placement.
Drawing notation: BRONZE RAIL; SEE DETAIL SH. 213; HALF PLAN; CENTER LINE OF ENTRANCE; 7'-0"
Section C-C establishes the stair-following profile; the HALF PLAN establishes the local centerline offset. W-201 local arrangement evidence only; no canonical world insertion is established.
