Gabriel Brown 23141673a2 Hang the Control Center where every other popover hangs
Five surfaces sat 12 pixels under the bar -- the date menu, the activity panel,
notification toasts, signal glass and the clipboard, all using barGap * 2. The
Control Center sat at 2, through a constant of its own, which left the widest
surface in the shell hanging ten pixels higher than the date menu beside it.

That constant arrived with the original Control Center and carried no reason,
while barGap directly above it explains itself. The clipboard even cites
QuickSettings in a comment for how it derived its own margin, and still landed
on 12. It reads as an early value nothing else converged on rather than a
decision, which is why it is going rather than being documented and kept.

The contract that guarded it pinned the literal, and that same file already
records where pinning a literal led: it once asserted the buggy margin
expression, so the code and the test agreed and a 38-pixel gap was invisible to
both. Replacing one number with another would have repeated it. It now reads the
top margin out of the Control Center and out of the date menu and requires them
to match, so drift in either direction fails -- verified by moving each one in
turn and watching it break.

# The margin is the GAP alone. This used to assert the bar height plus the gap,
# which is what the code said and what made the panel open 38 pixels below a bar
# it was written to sit 2 pixels under: an exclusiveZone of 0 already places the
# surface below the bar's reserved space, so naming the bar height again counted
# it twice. The contract agreed with the code and so the bug was invisible to
# both. layer-margin-contract now holds that rule for every surface.
# Asserted as a RULE rather than a literal, and derived from two files so that
# drift in either direction fails. The Control Center used to carry its own gap
# constant set to 2 while every other popover used barGap * 2, leaving the widest
# surface in the shell hanging ten pixels higher than the date menu beside it.
# Pinning the new number here would repeat the mistake this file already records
# below: a contract that agrees with the code cannot see the code being wrong.
