# End-to-End Contract System Demo — Section Design Reference Schema: Design Details SECTION.md v3.2 Source: https://spellbook.com/ Website: Spellbook Section ID: 1bc3bf0c-aba8-43c5-9523-1f31f97a5478 Status: deterministic evidence partially captured; editorial AI review pending ## Purpose This is a product-demo section on the Home page. Use the attached crop and measured browser facts to reconstruct its composition. Do not infer unmeasured source values. ## Layout captured layout ## Visual signature editorial, corporate, minimal, dark-mode-accented treatment at 1440×738px. The crop spans 1614–2352px of a 8091px page. ## Components - Announcement Bar - Navigation Bar - Hero With Background Imagery - Logo Strip - Testimonial Card - Feature Collection - Stat Block - Newsletter Form - Contact Form - Footer - Editorial News Block - Interactive UI Mockup ## Evidence note The geometry, typography, colors, media, and animation parameters below come from saved HTML/CSS/browser evidence when present. Website-level roles are supplied separately. Editorial section judgment remains pending unless the MCP resolves this source ID to a promoted canonical record. ## Build blueprint v3.2 ### Purpose and classification - Canonical type: product demo - Source type: product-demo - Structure: captured layout - Layout: captured layout - Styles: editorial, corporate, minimal, dark-mode-accented - Components: Announcement Bar, Navigation Bar, Hero With Background Imagery, Logo Strip, Testimonial Card, Feature Collection, Stat Block, Newsletter Form, Contact Form, Footer, Editorial News Block, Interactive UI Mockup - Purpose: product-demo section from the Home page of Spellbook. - Visual signature: Captured visual surface with captured layout. Inspect the crop for image and content hierarchy. ### Crop and composition - Crop: 1440×738px; aspect ratio 1.951:1 - Page bounds: 1614–2352px of 8091px - Guidance: Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured. ### Exact typography evidence The sectionScale values were measured inside this crop. The siteRoles values explain how those faces function across the source website; they must not replace section measurements. ```json { "sectionScale": [ { "role": "section heading", "family": "Soehne", "stack": "Soehne, Arial, sans-serif", "size": "20px", "weight": "400", "lineHeight": "28px", "letterSpacing": "normal", "sample": "Review contracts, draft agreements, and keep every position consistent across the deal-before and af", "element": "p", "occurrences": 12, "sourceId": "font-2" }, { "role": "section heading", "family": "Arizona Mix", "stack": "\"Arizona Mix\", sans-serif", "size": "51.2px", "weight": "300", "lineHeight": "56.3px", "letterSpacing": "-1.5px", "sample": "The first AI system that powers contracts end-to-end", "element": "h2", "occurrences": 7, "sourceId": "font-4" }, { "role": "UI/supporting text", "family": "Soehne", "stack": "Soehne, Arial, sans-serif", "size": "16px", "weight": "400", "lineHeight": "20.8px", "letterSpacing": "normal", "sample": "Catches non-standard terms across vendor agreements.", "element": "div", "occurrences": 26, "sourceId": "font-10" } ], "siteRoles": [ { "role": "display", "size": "68px", "family": "Arizona Mix", "source": "computed", "traits": "Regular", "weight": "300", "evidence": "font-6: computed CSS at 1440×1000; AI role: Arizona Mix, 300 weight, 68px size, -2.7px letter spacing.

Functional roles come from the website-level classifier and remain separate. ```json { "sectionUsage": [ { "value": "#56595B", "cssValue": "rgb(86, 89, 91)", "alpha": 1, "appliedAs": [ "border", "text" ], "occurrences": 22, "sourceId": "color-7" } ], "functionalPalette": [ { "hex": "#0E1315", "name": "canvas", "role": "canvas", "source": "computed", "evidence": "color-1: computed rgb(14, 19, 21); AI role: Deep charcoal (#0E1315) used extensively for the main backgrounds of the hero, header, form section, and footer.", "sampleId": "color-1", "confidence": 1 }, { "hex": "#FFFFFF", "name": "surface", "role": "surface", "source": "computed", "evidence": "color-3: computed rgb(255, 255, 255); AI role: White (#FFFFFF) used for alternating section backgrounds (like the logo strip and tools section) and cards to contrast the dark canvas.", "sampleId": "color-3", "confidence": 1 }, { "hex": "#F94D1E", "name": "primary action", "role": "primary-action", "source": "computed", "evidence": "color-10: computed rgb(249, 77, 30); AI role: Vibrant orange (#F94D1E) used for the top announcement bar background and call-to-action buttons (newsletter submit).", "sampleId": "color-10", "confidence": 0.95 }, { "hex": "#000000", "name": "text", "role": "text", "source": "computed", "evidence": "color-4: computed rgb(0, 0, 0); AI role: Black (#000000) used for text on white surfaces, ensuring high contrast.", "sampleId": "color-4", "confidence": 0.9 }, { "hex": "#D9D9D9", "name": "text", "role": "text", "source": "computed", "evidence": "color-6: computed rgb(217, 217, 217); AI role: Light grey/off-white (#D9D9D9) used for readable body text against the dark #0E1315 canvas.", "sampleId": "color-6", "confidence": 0.85 }, { "hex": "#56595B", "name": "border", "role": "border", "source": "computed", "evidence": "color-7: computed rgb(86, 89, 91); AI role: Mid-grey (#56595B) used for subtle borders and structural dividers.", "sampleId": "color-7", "confidence": 0.8 } ] } ``` ### Design tokens ```json { "radius": "Minimal. Mostly square or slightly softened corners on cards and buttons.", "density": "Low to medium density. The design prioritizes whitespace and readability over packing information tightly, aligning with the editorial style.", "evidence": "Observed from the structural layout, generous margins around the 'The complete contract AI suite' headline, 1px lines dividing the logo strip grid, and the styling of the 'Book a Demo' buttons.", "borderStyle": "Thin, subtle borders. Used sparingly, mostly as 1px solid lines (#D9D9D9 or #56595B) to divide sections or outline subtle cards.", "buttonStyle": "Solid and outline variants. Primary buttons (like 'Book a Demo') are solid white on dark backgrounds or dark text on light backgrounds. Arrow/icon buttons use the primary action color (#F94D1E).", "cornerStyle": "Slightly rounded to sharp. Buttons and inputs often have small, subtle border radii (e.g., 2px-4px visually), maintaining a structured, slightly sharp corporate aesthetic rather than fully pill-shaped.", "contentWidth": "Wide, constrained max-width. Content is centered within a generous container, likely around 1200px-1440px wide, leaving comfortable margins on desktop.", "spacingRhythm": "Generous spacing. Large vertical padding between major sections (often 100px+ visually) to maintain a clean, airy feel. Components within sections use tighter, structured grouping." } ``` ### Reconstruction specification This is the implementation contract for the captured desktop viewport. Prefer section-specific facts here over general website descriptions. - Root container was not deterministically isolated. - Layout containers: 0; cards/surfaces: 0; media elements: 0; browser animations: 0. #### Container, grid, and spacing ```json { "viewport": { "width": null, "captureBounds": null }, "container": null, "spacing": { "observedGapsPx": [], "representativeContentWidthsPx": [] }, "columns": [] } ``` #### Cards and surfaces ```json { "cards": [], "surfaces": null } ``` #### Media treatment ```json [] ``` #### Browser-exposed animation parameters ```json [] ``` ### Measured geometry, surfaces, media, and animation These raw values come from the saved element map and computed styles. Empty arrays mean the fact was not captured; they are not permission to invent source values. ```json null ``` ### Observed motion No timestamped authored motion is attached. Use only restrained baseline transitions. The browser animation records above are deterministic parameters captured from active browser animations. The timestamped observations describe what Gemini saw in the video. Treat them as complementary evidence. When either source is empty or they conflict, state the uncertainty instead of inventing timing or easing. ### Responsive contract - Measured viewport: unknownpx wide. - Mobile/tablet values: not measured by this section evidence unless a separate capture is explicitly listed. - Preserve hierarchy and sequence; collapse simultaneous columns only where needed, maintain media aspect ratios, and verify touch targets and text wrapping at target breakpoints. ### Structure versus visual skin - Preserve: content hierarchy, layout relationships, section rhythm, interaction purpose. - Adapt: brand colors, font family, copy, imagery, icons, decorative details. - Rule: Preserve the observed design logic while creating original branding, copy, assets, and implementation details. ### Adaptation and dependencies - Effort: Not assessed - What transfers: Documented hierarchy and composition - Dependencies: None recorded - Guidance: Adapt the pattern to the new product and content. ### Evidence readiness - Coverage: 6/7 - Can build: Yes - Missing facts: section-level geometry, surfaces, media treatment, and animation parameters; timestamped authored motion - Warning: Buildable with adaptations for these unsupported facts: section-level geometry, surfaces, media treatment, and animation parameters; timestamped authored motion. ### Agent implementation prompt Create an original product demo section inspired by the design evidence titled “End-to-End Contract System Demo”. Purpose: product-demo section from the Home page of Spellbook. Structure: captured layout. Source layout label: captured layout. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured. Visual signature to preserve at the pattern level: Captured visual surface with captured layout. Inspect the crop for image and content hierarchy. Components: Announcement Bar, Navigation Bar, Hero With Background Imagery, Logo Strip, Testimonial Card, Feature Collection, Stat Block, Newsletter Form, Contact Form, Footer, Editorial News Block, Interactive UI Mockup. Style direction: editorial, corporate, minimal, dark-mode-accented. Observed crop: 1440×738px (1.951:1). Treat this as evidence of composition, not a mandatory output size.

Do not invent signature motion. Use only restrained baseline transitions if the product needs them. Transfer the documented hierarchy and composition rather than source copy or assets. No explicit dependencies were recorded. Adapt the pattern to the new product and content. Use new copy, imagery, branding, and implementation details. Do not reproduce the source website or its proprietary assets.
