Assets: replace the invented numbers with the measured ones

The assets were generated on Aug 26 against a pitch that no longer holds, and
their hero figures were composites. Every number in them is now real and
checkable.

The OG image led with "stalled 9d 04h" -- an invented duration on an invented
Safe. It now leads with the survey result: of 366 queued Safe transactions that
matched the naive ready-to-execute test across 1,299 Base Safes, 92.6% were
already dead. The right panel carries the funnel that produced it, 366 -> 339
dead -> 27 live -> 6 at nonce -> 2 simulating SUCCESS, and the oldest real
stall found in the wild, 522 days on a genuine 2-of-3 signed 35 minutes after
proposal.

The README hero claimed execution "from a non-owner Turnkey EOA". Turnkey
custody is unconfirmed (DX-3) and the README was already corrected to
"KeeperHub-controlled"; a shipped image contradicting the README in the first
place a judge looks is worse than either version alone. It now says "from a
wallet that owns nothing", and traces our actual execution end to end: nonce 0,
2/2 signed, 10 USDC, block 11618878, tx 0xf0b3b611...cc68. The threshold meter
and blob segments were reduced from three to two to match, because a diagram
whose parts disagree reads as decoration rather than a record.

The YouTube thumbnail and Devpost gallery carried the same invented duration
and now carry 522d.

The export pipeline earned its keep twice: it refused to ship when the new
funnel CSS asked for JetBrains Mono 700 and only 400/500/600 were requested, so
the numbers would have silently rendered in a fallback face; and its byte
limits and dimension assertions passed on every re-export. Layout was checked
by measuring bounding-box overlap rather than by eye.
