# Agency benefit with board screenshot — Section Design Reference Schema: Design Details SECTION.md v3.2 Source: https://www.onmarathon.com/ Website: Marathon Section ID: af7080c4-e67f-4084-80d5-845217ef22af Design Details page: https://designdetails.io/sections/onmarathon-com--home--features-af7080c4 Status: deterministic evidence captured; editorial AI review pending ## Purpose This is a features section on the Home page. Use the attached crop and measured browser facts to reconstruct its composition. Do not infer unmeasured source values. ## Layout 1440×581px root; block ## Visual signature minimal, typographic, corporate, saas-showcase, high-contrast-accent treatment at 1440×581px. The crop spans 4081–4662px of a 7568px page. ## Components - Announcement Bar - Navigation Bar - Hero - Feature Card - Feature Collection - Primary Button - Footer - Offset Feature Layout - App UI Mockup Container ## 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: features - Source type: features - Structure: 1440×581px root; block - Layout: 1440×581px root; block - Styles: minimal, typographic, corporate, saas-showcase, high-contrast-accent - Components: Announcement Bar, Navigation Bar, Hero, Feature Card, Feature Collection, Primary Button, Footer, Offset Feature Layout, App UI Mockup Container - Purpose: features section from the Home page of Marathon. - Visual signature: rgba(0, 0, 0, 0) with 1440×581px root; block. Inspect the crop for image and content hierarchy. - Place on the page: 7 of 11, after Feature collection (`onmarathon-com:feature_list_ui_c05`), before Feature collection (`f422560f-ff51-4d66-b032-ce86f9555134`) ### Crop and composition - Crop: 1440×581px; aspect ratio 2.478:1 - Page bounds: 4081–4662px of 7568px - 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": [], "siteRoles": [ { "role": "display", "size": "81.4px", "family": "graphik", "source": "computed", "traits": "Regular", "weight": "500", "evidence": "font-4: computed CSS at 1440×1000; AI role: Graphik at 81.4px, used for the main hero heading.", "sampleId": "font-4", "confidence": 0.95, "lineHeight": "81.4px", "letterSpacing": "normal" }, { "role": "heading", "size": "46.2px", "family": "graphik", "source": "computed", "traits": "Regular", "weight": "500", "evidence": "font-1: computed CSS at 1440×1000; AI role: Graphik at 46.2px, used for section headings like 'Thanks for everything.'.", "sampleId": "font-1", "confidence": 0.9, "lineHeight": "46.2px", "letterSpacing": "normal" }, { "role": "body", "size": "15px", "family": "Inter", "source": "computed", "traits": "Regular", "weight": "400", "evidence": "font-5: computed CSS at 1440×1000; AI role: Inter at 15px, used for primary multi-line paragraph text.", "sampleId": "font-5", "confidence": 0.95, "lineHeight": "22.5px", "letterSpacing": "normal" } ] } ``` ### Exact color evidence The section samples record where each computed value was used. Functional roles come from the website-level classifier and remain separate. ```json { "sectionUsage": [], "functionalPalette": [ { "hex": "#D7FD51", "name": "accent", "role": "accent", "source": "computed", "evidence": "color-6: computed rgb(215, 253, 81); AI role: #D7FD51 (neon green) used for the top announcement bar and bottom CTA section background.", "sampleId": "color-6", "confidence": 1 }, { "hex": "#FFFFFF", "name": "surface", "role": "surface", "source": "computed", "evidence": "color-1: computed oklch(1 0 0); AI role: #FFFFFF used for feature cards sitting on top of the off-white canvas.", "sampleId": "color-1", "confidence": 0.95 }, { "hex": "#0B0B0B", "name": "text", "role": "text", "source": "computed", "evidence": "color-4: computed oklch(0.15 0 0); AI role: #0B0B0B used for primary headings and strong text.", "sampleId": "color-4", "confidence": 0.95 }, { "hex": "#F7F7F7", "name": "canvas", "role": "canvas", "source": "computed", "evidence": "color-2: computed rgb(247, 247, 247); AI role: #F7F7F7 used as the primary background color for the page body.", "sampleId": "color-2", "confidence": 0.9 }, { "hex": "#717171", "name": "muted text", "role": "muted-text", "source": "computed", "evidence": "color-5: computed oklch(0.55 0 0); AI role: #717171 used for body paragraphs and secondary information.", "sampleId": "color-5", "confidence": 0.9 } ] } ``` ### Design tokens ```json { "radius": "Buttons appear as fully rounded pills; feature cards and image containers have a moderate corner radius, likely around 12px to 16px.", "density": "Low density. The layout breathes with significant negative space surrounding text blocks and UI mockups.", "evidence": "Visual inspection of the desktop screenshots confirms spacious layouts, pill buttons for 'Get Started', and subtle gray/white contrasts for surface definitions.", "borderStyle": "Mostly borderless design with depth achieved via subtle background color contrasts; very faint 10% black borders appear as dividers (e.g., under the nav bar).", "buttonStyle": "Solid fill with highly contrasting text, heavily rounded (pill shape), without visible borders or prominent drop shadows.", "cornerStyle": "Mixed but consistent: fully rounded for interactive elements, gently rounded for layout containers.", "contentWidth": "Content is constrained to a central column, leaving wide margins on standard desktop viewports.", "spacingRhythm": "Generous vertical spacing between major sections and components, emphasizing a relaxed and uncluttered layout." } ``` ### Reconstruction specification This is the implementation contract for the captured desktop viewport. Prefer section-specific facts here over general website descriptions. - Root: 1440×581px; block; padding {"top":"44px","right":"0px","bottom":"44px","left":"0px"}; gap normal; background rgba(0, 0, 0, 0); radius 0px. - Representative content widths: 575, 410, 360, 343px. - Layout containers: 0; cards/surfaces: 0; media elements: 1; browser animations: 0. #### Container, grid, and spacing ```json { "viewport": { "width": 1440, "captureBounds": { "top": 4081, "bottom": 4662, "pageHeight": 7568 } }, "container": { "size": "1440×581px", "position": "x 0px, y 4081px", "display": "block", "positionMode": "static", "padding": { "top": "44px", "right": "0px", "bottom": "44px", "left": "0px" }, "margin": { "top": "0px", "right": "0px", "bottom": "0px", "left": "0px" }, "gap": "normal", "columns": "not captured", "background": "rgba(0, 0, 0, 0)", "radius": "0px", "border": "0px solid oklch(0.91 0 0)", "shadow": "none", "overflow": "visible" }, "spacing": { "observedGapsPx": [], "representativeContentWidthsPx": [ 575, 410, 360, 343 ] }, "columns": [] } ``` #### Cards and surfaces ```json { "cards": [], "surfaces": { "radii": [], "borders": [], "shadows": [] } } ``` #### Media treatment ```json [ { "element": "img · block h-auto w-full", "size": "575×380px", "position": "x 664px, y 4181px", "aspectRatio": 1.5, "objectFit": "fill", "objectPosition": "50% 50%", "radius": "0px", "overflow": "clip", "source": "https://onmarathon.com/_next/image?url=%2Fmarketing%2Fimages%2FShared-Project.png&w=1200&q=75" } ] ``` #### Browser-exposed animation parameters ```json [] ``` ### Measured geometry, surfaces, media, and animation These raw values come from the saved element map and computed styles.

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: 1440px 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-specific computed typography and color samples; timestamped authored motion - Warning: Buildable with adaptations for these unsupported facts: section-specific computed typography and color samples; timestamped authored motion. ### Agent implementation prompt Create an original features section inspired by the design evidence titled “Agency benefit with board screenshot”. Purpose: features section from the Home page of Marathon. Structure: 1440×581px root; block. Source layout label: 1440×581px root; block. Preserve the documented hierarchy and relationships; exact measurements were not deterministically captured. Visual signature to preserve at the pattern level: rgba(0, 0, 0, 0) with 1440×581px root; block. Inspect the crop for image and content hierarchy. Components: Announcement Bar, Navigation Bar, Hero, Feature Card, Feature Collection, Primary Button, Footer, Offset Feature Layout, App UI Mockup Container. Style direction: minimal, typographic, corporate, saas-showcase, high-contrast-accent. Observed crop: 1440×581px (2.478:1). Treat this as evidence of composition, not a mandatory output size.

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.
