README's *What is real and what is not* is one 84-line paragraph: give it the structure the rest of the file has #243

Pushed.

Split the single 84-line - Real. bullet under What is real and what is not into seven bold-lead subsections, nested under the same list item: The guns and penetration, The drop economy, Utility, Feedback, Sound and bodies, The bomb, and The leaderboard — in that order, matching the sequence the original prose already followed.

Not one sentence was added, removed or reworded; I only inserted the seven bold headers and paragraph breaks at the existing topic boundaries (verified by diffing the stripped text against the original, word for word). The one sentence that bridged two topics — "A footstep only carries so far, but the bomb's beep and the blast that ends it carry across the whole map." — was kept with The bomb rather than split off to The leaderboard, since it's still describing the beep's reach.

The Generated / Learned / Simulated / Signed bullets are untouched (confirmed byte-identical), so the five-way Real/Generated/Learned/Simulated/Signed distinction is still one glance down the same list. Nothing else in the file moved. bun run check passes (885 tests, 0 failures — the tsc→bun-test toolchain needed bun install for the dev-only typescript/@types/bun packages first, which was already the case before this change).

Closes #176
