Hero Prompt

# Hero banner — HD image-generation prompts (ai-dev-stack)

Generate at **1280×640 (2:1)** for the GitHub social-preview card, export PNG, replace `assets/hero.png`.
The README already references `assets/hero.png`, so the swap is automatic.

Three directions below — generate each in Google Labs / Imagen, pick the best.

---

## Prompt A — "Architectural blueprint" (recommended)

> Ultra-clean futuristic developer-tool hero banner, 1280×640, cinematic wide composition.
> Deep charcoal-to-near-black background (#0d1117) with a faint isometric blueprint grid and
> subtle volumetric light. Centered title **"ai-dev-stack"** in a crisp geometric sans-serif,
> pure white, with a single thin electric teal-to-violet gradient underline. Small tagline
> beneath in soft gray: **"Foundations × Pillars × Domains — the reusable kit for building with AI."**
> To the right, an elegant exploded-layer diagram floating in 3D: three translucent glass
> panels stacked and slightly offset, glowing at the edges — labeled subtly as foundation,
> pillar, domain — connected by thin luminous lines. Minimal line-art glyphs: a code bracket,
> an agent node, a looping automation arrow. Premium open-source aesthetic, high detail, soft
> bloom, no people, no faces, no logos, no stock-photo look, generous negative space, 8k, sharp.

Negative: clutter, busy background, real photography, watermark, lens flare overload, gradients on text other than the underline.

## Prompt B — "Neural circuit" (techy, bolder)

> Futuristic AI engineering banner, 1280×640. Dark indigo background with a glowing circuit-
> board / neural-graph texture fading from dense (one side) to sparse negative space (other).
> Big bold **"ai-dev-stack"** wordmark in white with a faint teal glow; one-line tagline below.
> Nodes pulse along thin light-traces that resolve into three labeled clusters. Electric teal +
> violet accents on a near-black field, high contrast, crisp typography, cinematic depth of
> field, premium, minimal, no faces, no logos, 8k.

Negative: messy, neon overload, unreadable text, photographic humans.

## Prompt C — "Light minimal" (alt for light-mode README)

> Minimal premium banner, 1280×640, soft off-white background (#f6f8fa) with a faint dotted
> grid. Bold near-black **"ai-dev-stack"** wordmark, a slim teal→violet underline, and a thin-
> line isometric three-layer stack illustration on the right in graphite line-art. Lots of
> whitespace, elegant, editorial, no photography, no logos, 8k, razor-sharp.

## Notes
- Keep text large + legible (the card is cropped to ~2:1 in feeds/search).
- Optional 640×640 square variant for social posts.
- Keep the teal→violet accent consistent with the companion `ai-automation-kit` banner.
