Relocated Leaderboard button to breadcrumb row on mobile, converted section pills to a proper sliding tab bar with active underline indicator, and updated Break Hit Calculator box format tabs with active purple fill state.
Athlete Page — Mobile UI Refinements
Relocated the Leaderboard button to sit inline on the breadcrumb row (left: back link, right: Leaderboard button) on mobile. Replaced the old pill-style section tabs with a proper full-width sliding tab bar — active tab shows bold text with a sliding purple underline indicator (CSS transform transition). Tapping a tab now switches visible content inline instead of anchor-scrolling. Break Hit Calculator box format tabs (Hobby/Jumbo/Value/etc.) now use a purple filled background with white text for the active state. Desktop layout unchanged.
