Since commit 6a9dea943c07 ("Add a new 'check' stage in assemble()"),
nasm is now able to detect unused labels. This was then tried on this
repository the cleanup labels which were never used.

Use the new asan:stack statement2026-04-08T14:10:41ZMiquel Sabaté Solàmssola@mssola.com2026-04-08T14:10:41Zurn:sha1:c3c6f3b4469bf9eadff5763fa16dbbbf15637e57
This allows us to account for the stack on the memory report. Using half
of the $100 page for stack management is most surely overblown, but I
have not really computed how much we are using the stack on this game,
even if I suspect that its usage is actually pretty minimal. Anyways, we
have room to spare in RAM space, so let's reserve half a page for the
stack.

Clear out sprites after the take off animation2026-04-06T19:43:44ZMiquel Sabaté Solàmssola@mssola.com2026-04-06T19:43:44Zurn:sha1:f9ca8ca80b9d0cf0d54f9aa59a3fbb517c37fc9c
This was hidden before commit 134c671e18b6 ("Cancel the take off
animation before shuttle change"), as the sprites and the background
matched perfectly. That wasn't the case in the case where the shuttle
kind was to change.

Just as it was on the original game, if we cleared the stage right
before changing the shuttle kind, then we don't go down again.

We want every shuttle kind to appear at least once before rewarding the
player with the coin.
