Merge branch 'main' of https://git.prox.ws/BERGVOLT/Materialschein

.proj-name, .detail-title und die mobile Karten-Bezeichnung (.td-bez) hatten
color:#fff fix codiert statt var(--text) - auf dunklem Grund unsichtbar
unproblematisch, im neuen Hell-Modus aber weiße Schrift auf weißer Karte.
Zusätzlich die native <select>-Options-Liste (label.field select option) auf
Hell umgestellt, war sonst dunkler Hintergrund mit jetzt ebenfalls dunklem
(unlesbarem) Text.
