Single-camera setup: removed CAM1-8 switcher nav, switchCamera()
function, and all .camBtn styles. ci is now permanently 0.
Wild Dragon SVG logo added to resources/ and rendered as a centered
background watermark (brightness(0) invert(1), 3.5% opacity) so it
reads as a faint white ghost on the dark theme without interfering
with any controls.
