Write down where all of this came from

Section G, the closeout.

UPSTREAM-INSPIRATION gains the second and largest borrowing round: what
was taken from omarchy, end-4, caelestia, ML4W and HyDE, what was
rebuilt rather than transplanted, and -- the part that matters more --
what was declined and why. Wallpaper-derived colour is declined on
identity, because dynamic colour is how rices end up looking like each
other. Audio visualisers are declined because a continuously repainting
equaliser is the GPU-pegging animation this project avoids. Patching
application internals to theme them is declined because the maintenance
is unbounded and lands on whoever is holding the desktop that day.

DESKTOP-PARITY gains a Portable machines section, which it has never
had, because until yesterday Panama was a desktop configuration in the
code as well as on the machine. Nine rows, one of them honest about not
having run on hardware with a lid. The remaining-gaps list gains the
four things now known to be missing rather than the one.

The README stops describing a desktop from before yesterday: migrations
in the install flow, the welcome and cheatsheet and manual, and laptops
working with every surface hiding itself where the hardware is absent.

The plan records its own outcome per section, including the two places
the work departed from it: D2's template renderer deferred once D1
removed the duplication it existed to fix, and E1 inverted after using
it for an afternoon.
