As vibld’s tokens
The palette on the 15+ color tokens vibld styles a project with, each text color on the fill it is read on. Marked tokens are solved from the palette, because no swatch held that role at 4.5:1.

Build prompt
The baseline every prompt in the catalog assumes, then this design’s own ten sections, from goal to guardrails.
The baseline
### How to use these prompts Each Cinematic Hero prompt describes one page: a full-bleed hero built around a single generated image, and one supporting section in the same style. The rules below apply to every one of them. ### Cinematic Hero principles - One full-bleed hero per page. The image is the subject, not decoration. - An oversized display headline of two to four words that runs past an edge or overlaps the subject. It is live text, never part of the image. - A tiny nav: a wordmark and three or four small links, one pill-shaped primary action, and at most one quiet secondary action. - The hero image returns as the page background, blurred 40 to 80px and darkened, so the hero sits in a card with 24 to 32px corners. - A tight palette: two or three colors taken from the image and one accent, used mostly on the primary action. - A distinct display face with a quiet body face. Small labels get wide tracking. - Small glass or chip details (a stat, a tag, an avatar row, a counter), never a wall of features. - One signature motion and a staggered text reveal. prefers-reduced-motion turns every loop off and shows still frames. - On phones the headline keeps its bleed at a clamp() size, the subject stays in frame, a video becomes its poster, and chips stack under the action. ### Engineering baseline - TypeScript strict mode, small typed components, and one source of truth for design tokens (CSS variables consumed by Tailwind). - All copy lives in one typed content file, so the owner can edit words without touching layout. - Every form validates on the client, says what went wrong in plain words beside the field, and never claims success it has not had. - No secrets in the bundle and no third-party scripts beyond Google Fonts.
### Goal Build **Obsidian Ring**: A product page for a single piece of hardware: a matte black smart ring. One macro render, one frosted card with name, price and pre-order. Nothing else competes. It is one cinematic hero and one supporting section, in the Cinematic Hero series. ### Stack React + TypeScript + Vite and Tailwind CSS. Motion in CSS and the Web Animations API. No backend: the page is static, and any form keeps its result on the page until the owner connects an endpoint. ### Pages & layout 1. Near-black page with the render blurred into a faint gray halo behind. 2. Tiny nav: wordmark left, three links right. 3. Macro ring render filling the left two thirds. 4. Frosted card on the right: name, one-line pitch, price and a ghost Pre-order button. 5. One supporting section: three numbers (battery, weight, depth rating) in large type with hairline dividers. Copy to start from, all in `content.ts`: headline "Obsidian", subcopy "Sleep, heart and recovery in 4 grams of titanium.", primary action "Pre-order". On phones the headline keeps its bleed at a clamp() size, the subject stays in frame, and chips stack under the action. ### Design system Mood: Precise, nocturnal, expensive. Black on black with one sweep of light. Palette: black `#0b0b0c`, graphite `#2a2a2c`, text `#ededed`. Tokens: background `#0b0b0c`, foreground `#ededed`, primary `#ededed` with `#0b0b0c` labels, cards `#2a2a2c`. Type: Michroma for product name and price, uppercase with wide tracking; Lexend Exa for spec lines, labels and the ghost button. Load both from https://fonts.googleapis.com/css2?family=Michroma&family=Lexend+Exa:wght@300;400&display=swap. Small labels in Lexend Exa with 0.12em tracking. Corners: 28px on the hero card, 16px on cards, pills fully round. Spacing: Near-black page; ring centered left at 60vh; frosted product card on the right, 360px wide, 28px padding. Hero image: A macro render of a matte black ring with a glossy inner rim catching a single line of light, on pure black. No text in the frame; empty space on the left. The series made this image for the design: https://vibld.com/img/cinematic/obsidian-ring.webp, 2688 by 1535, alt text "A matte black ring on black, one line of light along its glossy inner rim". Use it by that absolute URL, with `srcset="https://vibld.com/img/cinematic/obsidian-ring-800.webp 800w, https://vibld.com/img/cinematic/obsidian-ring-1600.webp 1600w, https://vibld.com/img/cinematic/obsidian-ring.webp 2688w"`, unless the person has uploaded a hero image of their own, which then takes its place. Never a placeholder photo or a stock image of people. ### Components & interactions - Frosted product card - Ghost button - Hairline stat row - Blurred hero echo background Motion: - Ring turns a few degrees as the page scrolls - A specular highlight sweeps across the rim every 6 seconds - Staggered reveal of card lines The signature motion is: A specular sweep across the rim. Keep it to that one; everything else is a 150 to 300ms state change. With prefers-reduced-motion, loops stop, videos show their poster and reveals are instant. ### Data & state All copy and the supporting section's items live in one typed `content.ts`. Inputs validate as the visitor types and report a result inline; nothing is sent anywhere until the owner connects a form endpoint. ### Accessibility WCAG 2.2 AA. The headline is real text, not part of the image, and the image has alt text describing it. Every control has a visible focus ring and a 44px target. Verified contrast: body text on the page #ededed on #0b0b0c 16.80:1; text on cards and chips #ededed on #2a2a2c 12.23:1; secondary text on muted surfaces #b5b5b5 on #222223 7.75:1; secondary text on the page #b5b5b5 on #0b0b0c 9.59:1; label on the primary action #0b0b0c on #ededed 16.80:1; label on secondary surfaces #ededed on #2a2a2c 12.23:1; label on the accent #ededed on #2a2a2c 12.23:1; error label #ffffff on #d93a3a 4.54:1; primary action against the page #ededed on #0b0b0c 16.80:1. ### Security No third-party scripts other than Google Fonts. Forms carry a hidden honeypot field and cap input length. ### Performance & SEO Serve the hero image as AVIF or WebP with its width and height, `fetchpriority="high"` and no lazy loading; the blurred echo reuses the same file with a CSS filter. Preconnect to Google Fonts. Title and meta description come from `content.ts`. Largest contentful paint under 2.5s on a mid-range phone. ### Guardrails - Avoid: Color accents, busy spec tables. - One accent color, one primary action, at most four nav links. - No carousel or slider in the hero, no mega menu, no emoji or clip-art icons, no hard offset shadows. - No purple-to-blue gradient and no stock photos of people at desks. - The brand is invented. Use no real company's name, logo or trademark.
