New /fitness/measure/body-parts route with step-by-step tape-measure flow, per-step tips, L/R paired inputs, inline history chart, and review-before-save summary. Measure page replaces the old body-parts accordion with a launch button. Fitness layout goes full-bleed and hides the site footer for this route via a :has() attribute selector, and the desktop 3-column grid now extends rail and side panel up past the floating nav while the middle column compensates with padding.
