Only the header's edge changes; row height (34.5px loading vs 39.5px loaded) is unchanged by this PR and is the residual #12886 already records.
How these were captured. Local dev servers bound to the propflow-stage table (anonymized by construction), signed in as the smoke login, desktop 1440×900. The loading screen is held on screen by an uncommitted local hook (a cookie-gated wait in the list's page.tsx) that is in no PR. Values are read from the rendered DOM. Before = origin/main; after = this PR's branch.
