Dark slide design prompts

Dark decks own the room: on a big screen in low light, a near-black slide with bright type looks like cinema while white slides look like documents. Midnight Pitch and Monolith use that drama for fundraising, Cinema and Marquee for creative work, and Mainframe, Circuit and Telemetry give technical content the glow of a terminal.

Dark mode fails when contrast is left to chance, so these prompts pin the exact background, text and accent hexes and ban low-contrast gray-on-black pairings. Charts get their own rules, since default chart colors are designed for white canvases.
