# Particle Contact CTA Schema: Design Details SECTION.md v3.2 Website: Sentient Source: https://sentient.foundation/ Source section IDs: gap-ac138aba-4742-5942, 0fdf82a0-b7d0-46e5-b3bc-071b0c94a52e Status: AI analysed; vocabulary promotion is automated ## Classification - Type: cta - Layout: full-width background with overlaid particles and text - Styles: minimal, illustrative - Confidence: 95% ## Purpose and structure A contact section featuring a grayish-blue background, subtle scrolling code, and a particle animation that forms into a shape. Visual signature: A grayish-blue background with faint scrolling code and an abstract, flower-like shape made of white dots. ## Components - particle animation - code overlay - typography ## Typography - Display: Neurialgrotesk — 65px 500 - Heading: Neurialgrotesk — 40px 500 - Body: Neurialgrotesk — 14px 500 - Mono: Geistmono — 12px 400 ## Functional palette - Canvas: canvas #F9F8F6 - Text: text #0E0C0C - Border: border #000000 - Surface: surface #718698 ## Motion evidence - 18.0–22.0s — The white background fades to a greyish-blue. A large 'SF' logo outline appears briefly in the top right. Code snippets scroll down the left side. Text appears on the left, and a new particle shape forms in the center. (94% confidence) ## Section quality Overall: 61.50/100 (Good) Scored coverage: 100% - Typography: 58 — Clean large sans-serif headline paired with monospace labels and code-style background text creates a legible two-tier system, but the hierarchy is simple (one headline, two small label lines) with no distinctive type craft beyond size contrast. Next tier: Needs more deliberate type pairing or scale variation beyond a single headline and small caption labels to read as more than a standard CTA treatment. - Composition: 65 — Strong use of negative space: headline anchored top-left, metadata labels top-right, and a large particle motif occupying the lower two-thirds creates clear asymmetric balance and breathing room across a tall full-bleed canvas. Next tier: The composition relies on a single centered focal graphic with conventional corner-anchored text; it lacks a secondary compositional move (e.g., grid interplay, layered depth) that would push it into memorable territory. - Motion: 62 — Gemini's timestamped detail (18-22s) describes a coordinated sequence: background color fade, brief logo reveal, scrolling code, and particle shape formation, indicating a reasonably crafted multi-layer transition rather than a single reveal effect. Next tier: Only one motion beat is documented; without evidence of how the particle shape itself animates (formation choreography, easing, interaction) it reads as competent rather than exceptional. - Content: 64 — The dandelion/flower particle form echoes a growth metaphor tied directly to the copy ('Sentient grows with every interaction'), and the faint scrolling code reinforces the AI/engineering context, giving the visual a clear conceptual link to the message. Next tier: The metaphor, while fitting, is a single visual idea not reinforced elsewhere in the section (e.g., no supporting micro-copy or iconography extending the concept). - Originality: 60 — Particle-formed shapes and code-texture backgrounds are now a recognizable convention in tech/AI marketing sites; the dandelion motif adds a thematic twist but the overall device is not distinctive. Next tier: Needs a visual or interaction idea that isn't a now-common particle-reveal trope to stand out as original rather than well-executed familiar technique. - Adaptability: 60 — Deterministic facts show clearly separable layers (top gradient canvas, particle video, bottom gradient canvas, SVG logo, and independent text blocks), making it straightforward to swap typography, palette, or the particle asset without disturbing the layout skeleton. Next tier: Full separation confidence is limited since the particle effect is delivered via a baked video asset rather than a parametrized animation system, constraining true motion reusability. Strengths: - Clear asymmetric layout with generous negative space directing focus to the particle centerpiece - Thematic coherence between the dandelion particle metaphor and the 'grows with every interaction' copy - Layered background texture (faint code) adds depth without competing with foreground content Weaknesses: - Typography system is minimal, relying on scale alone for hierarchy - Particle-formation device is a common technique in current AI/tech site design - Motion evidence covers only one transition window, limiting insight into the full animation's craft - Particle effect is delivered as a baked video rather than a reusable animated system Why it does not reach the next tier: The section is well-composed and thematically coherent but depends on a widely used particle-reveal convention and a single documented motion beat; it lacks the layered typographic or compositional sophistication, or a genuinely novel motion idea, needed to feel singular and hard to substitute. ## Adaptation guidance - Effort: Medium - Guidance: Recreate the layered structure (background texture canvas + centered focal visual + corner text labels) with any brand-appropriate particle or generative visual, replacing the specific video asset; typography and copy can be swapped freely since the layout grid and hierarchy are independent of the specific type choices. What transfers: - Asymmetric text placement with large negative space below - Layered background texture (subtle motion/code pattern) behind a centered focal graphic - Small caption/label pairing in opposing corners for secondary information Dependencies: - Baked video asset for the particle formation effect - Specific color-fade transition between viewport scroll states - Custom canvas-based gradient backgrounds ## Living vocabulary - No reusable vocabulary candidates were supported by this section. Only terms with status `active` enter the public taxonomy. Deferred and proposed terms remain available to later AI passes; rejected terms remain as provenance so they are not repeatedly reinvented. ## Provenance and limitations - Section boundaries and naming: Gemini Pro visual observation - Motion observations: Gemini Pro direct-video analysis - Quality judgment: Claude - Exact design facts: browser/CSS extraction at website scope - Rubric: Design Details section rubric 3.2 (Typography 20%, Composition 20%, Motion 15%, Content 15%, Originality 15%, Adaptability 15%) - Motion scoring is based on a single timestamped transition window; the full particle animation's internal choreography is not described - No deterministic data on letter-spacing or weight variation within the headline to assess finer typographic nuance - Adaptability assessment assumes the video-based particle effect could be replaced with an equivalent generative system, which is not confirmed by evidence ## Usage guidance Use this section as design evidence. Create an original implementation; do not reproduce the source copy, assets, or proprietary composition exactly. ## Build blueprint v3.2 ### Purpose and classification - Canonical type: cta - Source type: cta - Structure: full-bleed - Layout: full-width background with overlaid particles and text - Styles: minimal, illustrative - Components: particle animation, code overlay, typography - Purpose: A contact section featuring a grayish-blue background, subtle scrolling code, and a particle animation that forms into a shape. - Visual signature: A grayish-blue background with faint scrolling code and an abstract, flower-like shape made of white dots. ### Crop and composition - Crop: 1440×1139px; aspect ratio 1.264:1 - Page bounds: 5942–7081px of 12930px - Guidance: Let the primary media establish the section boundary and protect legibility with controlled overlays. ### 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": "65px", "family": "Neurialgrotesk", "source": "computed", "traits": "Regular", "weight": "500", "evidence": "font-3: computed CSS at 1440×1000; AI role: Large 65px Neurialgrotesk used for major section headings ('Where AI learns to feel...', 'Open AGI Summit').", "sampleId": "font-3", "confidence": 0.9, "lineHeight": "71.5px", "letterSpacing": "-0.6px" }, { "role": "heading", "size": "40px", "family": "Neurialgrotesk", "source": "computed", "traits": "Regular", "weight": "500", "evidence": "font-1: computed CSS at 1440×1000; AI role: 40px Neurialgrotesk used for primary narrative text and subtitles in the hero and other sections.", "sampleId": "font-1", "confidence": 0.9, "lineHeight": "44px", "letterSpacing": "normal" }, { "role": "body", "size": "14px", "family": "Neurialgrotesk", "source": "computed", "traits": "Regular", "weight": "500", "evidence": "font-6: computed CSS at 1440×1000; AI role: 14px Neurialgrotesk used for general descriptive body text.", "sampleId": "font-6", "confidence": 0.8, "lineHeight": "16.8px", "letterSpacing": "normal" }, { "role": "mono", "size": "12px", "family": "Geistmono", "source": "computed", "traits": "Regular", "weight": "400", "evidence": "font-7: computed CSS at 1440×1000; AI role: 12px Geistmono used extensively for code snippets and secondary information.", "sampleId": "font-7", "confidence": 0.95, "lineHeight": "15px", "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": "#F9F8F6", "name": "canvas", "role": "canvas", "source": "computed", "evidence": "color-1: computed rgb(249, 248, 246); AI role: Off-white #F9F8F6 used as the primary background color when canvas elements are not covering the viewport (e.g., news and footer sections).", "sampleId": "color-1", "confidence": 0.9 }, { "hex": "#0E0C0C", "name": "text", "role": "text", "source": "computed", "evidence": "color-9: computed rgb(14, 12, 12); AI role: Near-black #0E0C0C used for text in the light-themed lower sections (footer).", "sampleId": "color-9", "confidence": 0.9 }, { "hex": "#000000", "name": "border", "role": "border", "source": "computed", "evidence": "color-8: computed rgb(0, 0, 0); AI role: Black #000000 used for borders in the news feed list.", "sampleId": "color-8", "confidence": 0.85 }, { "hex": "#718698", "name": "surface", "role": "surface", "source": "computed", "evidence": "color-2: computed rgb(113, 134, 152); AI role: Slate blue #718698 associated with canvas containers and text over specific backgrounds.", "sampleId": "color-2", "confidence": 0.7 } ] } ``` ### Design tokens ```json { "radius": "Buttons appear fully rounded (pill shape), while most structural elements and images have sharp, 0px border-radii.", "density": "Very low density overall, prioritizing visual impact and motion over information density.", "evidence": "Observation of layout crops and DOM facts: use of '.layout_grid' for full viewport control, minimal button styles, and wide distribution of text nodes.", "borderStyle": "Thin, solid, 1px lines used sparingly as dividers in lists (news feed, footer).", "buttonStyle": "Minimalist outline style (pill-shaped) for primary actions, or simple inline text with brackets for secondary actions.", "cornerStyle": "Mix of sharp corners (bracketed links, general layout) and pill shapes (header button).", "contentWidth": "Full-bleed for media backgrounds, with text elements often constrained to specific columns or wide margins spanning the full viewport width.", "spacingRhythm": "Sparse and expansive. Content is often placed at edges or vertically centered with massive amounts of negative space to allow background visuals to take precedence." } ``` ### 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. - Observed gaps: 8px. - Representative content widths: 580px. - Layout containers: 0; cards/surfaces: 0; media elements: 1; browser animations: 0. #### Container, grid, and spacing ```json { "viewport": { "width": 1440, "captureBounds": { "top": 5942, "bottom": 7081, "pageHeight": 12930 } }, "container": null, "spacing": { "observedGapsPx": [ 8 ], "representativeContentWidthsPx": [ 580 ] }, "columns": [] } ``` #### Cards and surfaces ```json { "cards": [], "surfaces": { "radii": [], "borders": [], "shadows": [] } } ``` #### Media treatment ```json [ { "element": "video · video", "size": "1440×740px", "position": "x 0px, y 6359px", "aspectRatio": 1.9, "objectFit": "cover", "objectPosition": "50% 50%", "radius": "0px", "overflow": "clip", "source": "https://sentient.foundation/assets/video/987601c7_698daec2aaf157233be3207f_Flower_gpt2_mp4.mp4" } ] ``` #### 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 { "root": null, "cards": [], "media": [ { "id": "ld-309", "tag": "video", "rect": { "x": 0, "y": 6359, "width": 1440, "height": 740 }, "role": null, "label": "video", "media": { "src": "https://sentient.foundation/assets/video/987601c7_698daec2aaf157233be3207f_Flower_gpt2_mp4.mp4", "poster": "", "duration": 11.6 }, "radius": "0px", "overflow": "clip", "objectFit": "cover", "aspectRatio": 1.9, "objectPosition": "50% 50%" } ], "bounds": { "top": 5942, "bottom": 7081, "pageHeight": 12930 }, "schema": "little-details-section-measurements-v1", "source": "saved DOM/CSS element and animation maps", "columns": [], "spacing": { "gapsPx": [ 8 ], "representativeContentWidthsPx": [ 580 ] }, "coverage": { "cards": 0, "media": 1, "animations": 0, "elementsInSection": 8 }, "surfaces": { "radii": [], "borders": [], "shadows": [] }, "animations": [], "capturedAt": "2026-10-21T17:55:08.406Z", "limitations": [ "Values describe the captured desktop viewport and may change at other breakpoints.", "Transforms, sticky layers, and virtualized content can make the inferred section root approximate.", "Animations include browser-exposed Web Animations API state; CSS or script motion that was inactive at capture time may be absent." ], "viewportWidth": 1440 } ``` ### Observed motion 1. **scroll** — The white background fades to a greyish-blue. A large 'SF' logo outline appears briefly in the top right. Code snippets scroll down the left side. Text appears on the left, and a new particle shape forms in the center. (18s–22s; 94% confidence). Recreate the interaction principle with project-appropriate timing and easing; the evidence does not guarantee source easing values. 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: medium - What transfers: Asymmetric text placement with large negative space below; Layered background texture (subtle motion/code pattern) behind a centered focal graphic; Small caption/label pairing in opposing corners for secondary information - Dependencies: Baked video asset for the particle formation effect; Specific color-fade transition between viewport scroll states; Custom canvas-based gradient backgrounds - Guidance: Recreate the layered structure (background texture canvas + centered focal visual + corner text labels) with any brand-appropriate particle or generative visual, replacing the specific video asset; typography and copy can be swapped freely since the layout grid and hierarchy are independent of the specific type choices. ### Evidence readiness - Coverage: 6/7 - Can build: Yes - Missing facts: section-specific computed typography and color samples - Warning: Buildable with adaptations for these unsupported facts: section-specific computed typography and color samples. ### Agent implementation prompt Create an original cta section inspired by the design evidence titled “Particle Contact CTA”. Purpose: A contact section featuring a grayish-blue background, subtle scrolling code, and a particle animation that forms into a shape. Structure: full-bleed. Source layout label: full-width background with overlaid particles and text. Let the primary media establish the section boundary and protect legibility with controlled overlays. Visual signature to preserve at the pattern level: A grayish-blue background with faint scrolling code and an abstract, flower-like shape made of white dots. Components: particle animation, code overlay, typography. Style direction: minimal, illustrative. Observed crop: 1440×1139px (1.264:1). Treat this as evidence of composition, not a mandatory output size.
