Dark.style has no transparent template for an edit or a memo, so a StyleLookup at them fell back silently to the normal one and its grey background - the search field and the log were the last two things clashing with a painted interface. Since the style is vendored anyway, make-style.ps1 rebuilds it from Delphi's with those two backgrounds set to the palette. Reproducible, so a palette change does not quietly lose the patch.
The log is hidden now: it only serves diagnosis and it was taking a third of the screen at every launch. A Journal button beside the server settings brings it back.
