/* OlConnect Manager — strict black & white design system.
 *
 * One theme, no toggle. The panel had a lavender accent plus a light/dark
 * switch, which meant every visual decision had to work twice and the accent
 * competed with the status colours. Monochrome removes both problems: the
 * accent is gone, and meaning is carried by luminance (how bright a thing is)
 * and by shape, never by hue alone. Status stays readable for colour-blind
 * users because success/error also differ in weight and border, not just tone.
