- Root cause: Tailwind v4 space-y-* applies margin-block-end on :not(:last-child) children (verified in tailwindcss 4.2.1 dist), so #749's !mt-0 on the table wrapper had no effect — the 1rem gap came from margin-bottom on the floating header itself. - executive-meetings.tsx: added !mb-0 to em-sticky-thead div; kept !mt-0 on the wrapper as a harmless safeguard. - Header (border-t/x, no bottom) now sits flush on the table's border-2 top → single 2px seam. Sticky/translateX/print untouched. - tx-os tsc clean; architect review passed.
