Luxaudica 1.0.3

The free-tier mark now appears in four places instead of one, and reads
"Made with Luxaudica".

If you have bought a licence, nothing changes — your output stays clean.
If you are on the free tier, this is the visible difference, and it is
the only thing a licence removes. The app itself is untouched: every
scene, every control, every output still works exactly as before, free
and forever. Nothing locks.

Two scenes look better when the music peaks. Tunnel Run and Terrain used
to wash out at the drop — the tunnel drifted toward a pale teal and the
front blocks of Terrain bleached to near-white. They now hold their
colour, so a peak reads as brighter and more saturated rather than
flatter.

Under the hood: the mark can no longer fail silently. If the app cannot
draw it for any reason, it now marks the frame anyway rather than
handing back a clean one, and the projector output is checked in real
pixels the same way the main window already was.
