- 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.
