The match/skins identity banner (the "Match" card showing both players/sides + a status like "1 UP" or "AS") now renders as a territory bar in all three places it appears — round-detail.tsx's live Score tab, round-scorecard.tsx's post-round summary, and session-scorecard.tsx's tournament match view. The leading side's colored zone extends proportionally past the midpoint into the trailing side's half (capped so both names stay legible at extreme leads), and both sides are equal/neutral at AS or before any holes are scored — matching your sketch's idea directly.
Along the way I found and fixed a real overlap bug during browser testing: a long name could visually collide with the centered status pill on narrow (mobile) screens. Root cause was the identity box sizing itself to its own content instead of stretching to fill its zone — fixed so it always stretches, with alignment now handled via justify-start/end instead. Verified in both light/dark mode, normal and extreme leads, on a real scratch round matching your HCP scenario. Deployed live, teeoff.no unaffected.
