       page uses Radzen's own <RadzenLayout>. This app uses its own hand-rolled .app-layout shell
       instead, so that selector never matches and plain text (headings, paragraphs, labels —
       anything outside a themed Radzen component) silently fell back to the browser default black
       text color. That's invisible in the light theme (black-on-white) but unreadable in
       standard-dark (black-on-near-black) — this is the actual root cause of the "page headings
       and body text stay dark on dark background" defect. Body background is already handled by
       a separate, unscoped decorative rule in the same theme CSS, so only color needs setting
       here. */
