101 advanced JSON image-generation prompts (Gemini 2.5 Flash / 'Nano Banana') for the ENTROPY OS concept-art book, organized by function: - 00_art-direction: the visual canon (_ART_DIRECTION.md), JSON _TEMPLATE.json, worked _EXAMPLE.json - 01_key-art (9), 02_characters (16), 03_environments (14), 04_ui-menus (12), 05_key-moments (16), 06_hardware-props (12), 07_branding-ephemera (12), 08_motifs (10) Every prompt is a self-contained Nano-Banana-ready paragraph plus structured fields (aspect ratio, master-palette hexes, lighting, composition, text_in_image, period-anachronism avoid list, model tips). One visual language: beige-and-grey dominant, one accent glow per image, teal reserved for the ominous, locked to 1998-99. art/README.md indexes all 101.

"prompt": "The back-cover plate for the Collector's Edition: a single Win98-style progress bar, alone in pure black, stopped at 99.9%. The frame is almost entirely void black (#050505), a vast empty field with the faintest grain. Centered, small, sits one beveled administrative-beige (#c0c0c0) progress-dialog chrome — a thin sunken trough with the period 3D bevel — its fill rendered not in blue but in dim ENTROPY teal (#207878) that runs nearly the whole length and then, at the very last sliver, collapses and brightens into a single razor-thin pure-white line at the leading edge: the teal narrowing to white, the machine either powering down or being born. Above or below the bar, a tiny line of MS-Sans-Serif-style grey text reads '99.9%' and, fainter still, 'Completing operation… do not power off'. A whisper of white bloom haloes the final white line; the teal fill dims toward the trailing end as if energy is draining out of the world. Everything else is black — no icons, no horizon, no second light. Painterly digital concept art, matte filmic finish, extreme negative space, fine film grain, faint CRT scanline ghosting across the bar, slight chromatic aberration at the white edge, degraded 1999-scan look. Stark centered minimal composition, the single bar tiny against an overwhelming dark. Mood: hushed, terminal, sublime — the last 0.1% before the substrate so large it is indistinguishable from nothing; an ending and a beginning rendered as a stalled install.",
