/**
 * Issue #233: resize labels measure between wall faces, not between centrelines.
 *
 * Before the fix one bubble carried two conventions at once — lengths along the
 * centreline next to an area computed from the floor — so «3.00 × 4.00 · 11.0 m²»
 * described a room that no tape measure would confirm.
 *
 * The room below is 300×400 cm centre-to-centre with 15 cm walls on all four
 * sides, so every clear span is exactly 15 cm shorter than the axis it sits on:
 * 285 and 385 cm. Thickness is set through the card's own dialog path
 * (`_wallThickClick` → `_wallThickApply(true)`), and both label producers are
 * then called as the drag handlers call them. The legacy room-scale frame was
 * deliberately removed by #277, so only fixed-topology edge labels remain.
