Brand the app with the Wallace tartan and a Celtic splash

- The launcher icon is a single square of the tartan, drawn as a vector
  so it stays sharp at any density and ships no PNGs. The adaptive
  icon's foreground is deliberately empty: the cloth is the icon.
- Tartan.kt draws the sett as warp, then as weft at half opacity. That
  overlap is what gives the blended squares and reads as woven cloth
  rather than a printed grid, and it is reused by both the icon and the
  splash.
- The app opens on the tartan under "Pro Libertate Games" in Uncial
  Antiqua, holds two seconds, then fades. It is an overlay rather than a
  destination, so the menu is already composed behind it and the fade
  reveals a live screen. The window background is set to a dark red so
  launch does not flash white before Compose draws.

Two things to be aware of:

- WallaceSett is an approximation. It reads as Wallace — bold red and
  black check with a narrow gold overstripe — but the registered
  threadcount could not be verified here, so the counts were chosen to
  look right. They are plain data and can be swapped for the registered
  ones without touching anything else.
- Uncial Antiqua is bundled under the SIL Open Font License 1.1, with
  the full licence at docs/licenses/UncialAntiqua-OFL.txt. The OFL
  requires that to be distributed with the font, so it must not be
  separated from it.

+The goals of the Open Font License (OFL) are to stimulate worldwide

+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
