Moving Atoms — Worlds for Robot Learning opens with “A few images. A world of experiments.” in a center-aligned stacked hero. The homepage continues through 14 observed sections, moving from the opening proposition into Put an LLM agent at the controls, Put an idea in motion, From your camera to your next experiment. ## Color Dark surfaces use 8 repeated semantic colors; the primary action carries the strongest interactive emphasis. | Token | Value | Role | Usage | | --- | --- | --- | --- | | Canvas | `#090b0d` | Page canvas | Dominant rendered page background. | | Surface 1 | `#121618` | Surface | Repeated container or section fill; relative occurrence score 92. | | Surface 2 | `#101516` | Surface | Repeated container or section fill; relative occurrence score 45. | | Surface 3 | `#111719` | Surface | Repeated container or section fill; relative occurrence score 35. | | Primary text | `#f1f3ef` | Primary text | Observed display foreground with 17.7:1 contrast against the captured canvas. | | Secondary text | `#adb5af` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 9.4:1. | | Action | `#c5ef86` | Primary action | Fill used by the dominant first-viewport action. | | Border | `#2b3232` | Border and divider | Most repeated inspectable border color. | ## Typography A single-family system uses General Sans across display and reading roles, differentiated by size and weight. | Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color | | --- | --- | --- | --- | --- | --- | --- | --- | --- | | display | General Sans | 88px | 500 | 91.52px | -5.28px | normal | none | rgb(241, 243, 239) | | heading | General Sans | 60px | 500 | 66px | -2.7px | normal | none | rgb(241, 243, 239) | | body | General Sans | 15px | 400 | 26.25px | 0px | normal | none | rgb(173, 181, 175) | | body-small | General Sans | 11px | 400 | 19.8px | 0px | normal | none | rgb(173, 181, 175) | | label | General Sans | 10px | 400 | 16px | 0px | normal | none | rgb(151, 161, 155) | ## Spacing and shape - Base unit: 4px - Density: sparse - Maximum content width: 1344px - Section gap: 64px - Container padding: 18px - Common spacing: `18px`, `9px`, `10px`, `12px`, `24px`, `8px`, `20px`, `5px`, `64px`, `28px` - Corner strategy: Soft geometry is the dominant shape voice. Elevation is selectively reinforced with shadow. - Radii: Buttons `3px`, Containers `3px`, Pills `100px`, Media `3px`, Cards `0px` - Borders: `1px solid rgb(43, 50, 50)`, `1px solid rgb(53, 64, 60)`, `1px solid rgb(68, 82, 59)`, `1px solid transparent`, `1px solid rgba(174, 200, 152, 0.271)` - Shadows: `rgba(0, 0, 0, 0.267) 0px 3px 15px 0px`, `rgb(197, 239, 134) 0px -2px 0px 0px inset` ## Layout - Macrostructure: Stacked product narrative - Hero: Stacked hero: message leads into visual proof within the opening - Grid: 2 columns - Footer: Utility footer with 8 actions - Reading flow: The homepage continues through 14 observed sections, moving from the opening proposition into Put an LLM agent at the controls, Put an idea in motion, From your camera to your next experiment. - Section sequence: Put an LLM agent at the controls. → Put an idea in motion. → From your camera to your next experiment. → Keep the evidence. Take the environment. → Before your first experiment. → Bring your scene. See what your robot can do. → Give your agent a robot. → A photograph. A new kitchen. A zero-shot grasp. → Capture the scene → Make it a robot environment → Put your policy to work → Your policy, connected → Evidence you can inspect → A starting point for training ## Component grammar ### Hero Stacked, center-aligned opening anchored by “Build your environment”. - Role: Opening proposition - Observed instances: 1 - Pattern: `stacked` - Alignment: `center` - Heading: `General Sans · 88px / 500` - Media: `image-led` ### Navigation Static navigation with 8 visible actions in the desktop opening. - Role: Global wayfinding - Observed instances: 1 - Text: `#f1f3ef` - Border: `none` - Radius: `0px` - Padding: `0px 64px 0px 64px` - Type: `General Sans · 16px / 400` - Position: `static` - Height: `88px` ### Primary action “Build your environment” is the strongest first-viewport action by semantic intent and visual contrast. - Role: Conversion - Observed instances: 1 - Background: `#c5ef86` - Text: `#142010` - Border: `none` - Radius: `4px` - Padding: `14px 22px 14px 22px` - Type: `General Sans · 14px / 500` ### Content card 3 style-matched content card instances were found among 6 candidates; properties describe the dominant observed cluster. - Role: Repeated content module - Observed instances: 3 - Text: `#f1f3ef` - Border: `1px solid rgb(43, 50, 50)` - Radius: `0px` - Padding: `28px 0px 28px 0px` - Type: `General Sans · 16px / 400` - Candidate pool: `6` ### Badge or tag 1 style-matched badge or tag instance was found among 1 candidates; properties describe the dominant observed cluster. - Role: Compact status or category label - Observed instances: 1 - Background: `rgba(11, 19, 13, 0.902)` - Text: `#d7edc6` - Border: `1px solid rgba(174, 200, 152, 0.271)` - Radius: `3px` - Padding: `5px 8px 5px 8px` - Type: `General Sans · 9px / 400` - Candidate pool: `1` ### Media frame 2 style-matched media elements were found among 5 rendered candidates; cover fitting and 3px are the most repeated treatments. - Role: Visual proof - Observed instances: 2 - Fit: `cover, contain` - Ratios: `1.31, 1.32, 1.60, 1.33` - Radius: `3px, 0px, 4px` - Candidate pool: `5` ### Footer 8 visible actions close the page on a transparent surface. - Role: Closing navigation - Observed instances: 1 - Text: `#f1f3ef` - Border: `none` - Radius: `0px` - Padding: `48px 64px 24px 64px` - Type: `General Sans · 16px / 400` - Links: `8` ## Imagery Image led media acts as the page’s primary visual proof rather than decoration. Multiple visual elements share the first viewport. - Inventory: 4 images/canvas elements and 1 video across the analyzed homepage. - Treatment: cover fitting · 3px repeated radius ## Motion 0 declared keyframes and 0 active animations were inspectable at capture; observed timing uses 0.2s, 0.15s. - Libraries: CSS / browser-native or bundled source not identifiable - Durations: `0.2s`, `0.15s` - Easings: `ease`, `ease, ease` - Interaction states: disabled, hover, focus, active - Reduced-motion declaration found: yes ## Responsive behavior Measured at 390 × 844. - Desktop navigation reduces from 8 visible actions to 3. - Hero remains center-aligned; mobile heading size is 46.02px. - 5 multi-column content regions remain on mobile. - Horizontal overflow: not detected ## Do - Pair the observed #090b0d canvas with #f1f3ef primary copy before adding secondary surfaces. - Use General Sans at 88px/91.52px, weight 500, for the primary display moment. - Reserve the strongest first-viewport contrast for “Build your environment” within the center-aligned stacked hero. - Image led media acts as the page’s primary visual proof rather than decoration. ## Don’t - Do not mix in arbitrary radii; 3px is the repeated treatment on buttons. - Do not reuse the #c5ef86 action color across decorative elements; keep its interactive emphasis selective. - Do not introduce extra type families beyond General Sans. - Do not spread the observed shadow treatment across every container; keep elevation selective. ## Evidence - Hero: `/captures/moving-atoms/hero.webp` (960 × 600, scroll 0px) — Visible section: A few images. A world of experiments. - Mid-page: `/captures/moving-atoms/middle.webp` (960 × 600, scroll 2438px) — Visible section: Put an idea in motion. · A photograph. A new kitchen. A zero-shot grasp. - Closing: `/captures/moving-atoms/closing.webp` (960 × 600, scroll 4655px) — Visible section: Before your first experiment. · Bring your scene. See what your robot can do. - Mobile: `/captures/moving-atoms/mobile.webp` (390 × 844, scroll 0px) — Visible section: A few images. A world of experiments. ## Confidence notes - The hero heading was read from semantic heading markup. - 11 responsive breakpoint declarations were inspectable. - 2 stylesheets were inspectable; 0 cross-origin stylesheets were unavailable to rule inspection. - Computed styles describe the captured render; source design tokens and proprietary font files were not copied.
