## Visual thesis

Dark, center-aligned stacked product story with mixed geometry and image-led proof.

Enact opens with “The post-training layer for physical AI.” in a center-aligned stacked hero. The experience remains a single composed scene rather than a multi-section narrative.

## Color

Dark surfaces use 8 repeated semantic colors; the primary action carries the strongest interactive emphasis.

| Token | Value | Role | Usage |
| --- | --- | --- | --- |
| Canvas | `#0a0c0d` | Page canvas | Dominant rendered page background. |
| Surface 1 | `rgba(232, 232, 232, 0.043)` | Surface | Repeated container or section fill; relative occurrence score 1. |
| Surface 2 | `#f3eee4` | Surface | Repeated container or section fill; relative occurrence score 1. |
| Surface 3 | `rgba(243, 238, 228, 0.941)` | Surface | Repeated container or section fill; relative occurrence score 1. |
| Primary text | `#f3eee4` | Primary text | Observed display foreground with 17.0:1 contrast against the captured canvas. |
| Secondary text | `rgba(244, 237, 228, 0.62)` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 6.8:1. |
| Action | `rgba(243, 238, 228, 0.941)` | Primary action | Fill used by the dominant first-viewport action. |
| Border | `rgba(243, 236, 230, 0.161)` | Border and divider | Most repeated inspectable border color. |

## Typography

A single-family system uses Helvetica Neue across display and reading roles, differentiated by size and weight.

| Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| display | Helvetica Neue | 32px | 500 | 32px | -0.8px | normal | none | rgb(243, 238, 228) |
| body | Helvetica Neue | 16.8px | 400 | 26.04px | -0.168px | normal | none | rgba(244, 237, 228, 0.620) |
| body-small | Helvetica Neue | 11.84px | 500 | 15.984px | -0.0592px | normal | none | rgba(243, 238, 228, 0.522) |
| label | Helvetica Neue | 11.52px | 500 | 11.52px | -0.056px | normal | none | rgba(243, 238, 229, 0.420) |

## Spacing and shape

- Base unit: 8px
- Density: sparse
- Maximum content width: 1528px
- Section gap: 96px
- Container padding: 22\.5px
- Common spacing: `6.5px`, `96px`, `11.5px`, `22.5px`, `8px`, `12px`, `80px`, `20px`, `7.5px`, `18.5px`

- Radii: Pills `50px`, Media `0px`
- Borders: `1px solid rgba(243, 236, 230, 0.161)`, `1px solid rgba(243, 238, 228, 0.902)`

## Layout

- Macrostructure: Single-scene landing
- Hero: Stacked hero: message leads into visual proof within the opening
- Grid: 1 column
- Footer: Utility footer with 3 actions
- Reading flow: The experience remains a single composed scene rather than a multi-section narrative.
- Section sequence: No semantic section sequence detected

## Component grammar

### Hero

Stacked, center-aligned opening anchored by “Request data”.

- Role: Opening proposition
- Observed instances: 1
  - Pattern: `stacked`
  - Alignment: `center`
  - Heading: `Helvetica Neue · 32px / 500`
  - Media: `image-led`

### Navigation

Static navigation with 3 visible actions in the desktop opening.

- Role: Global wayfinding
- Observed instances: 1
  - Text: `#f3eee4`
  - Border: `none`
  - Radius: `0px`
  - Padding: `0px 0px 0px 0px`
  - Type: `Helvetica Neue · 16px / 400`
  - Position: `static`
  - Height: `12px`

### Primary action

“Request data” is the strongest first-viewport action by semantic intent and visual contrast.

- Role: Conversion
- Observed instances: 1
  - Background: `rgba(243, 238, 228, 0.941)`
  - Text: `#090a0b`
  - Border: `1px solid rgba(243, 238, 228, 0.902)`
  - Radius: `0px`
  - Padding: `11.52px 18.4px 11.52px 18.4px`
  - Type: `Helvetica Neue · 12px / 600`

### 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(243, 238, 227, 0.761)`
  - Text: `#090a0b`
  - Border: `none`
  - Radius: `0px`
  - Padding: `0px 0px 0px 0px`
  - Type: `Helvetica Neue · 10.4px / 500`
  - Candidate pool: `1`

### Media frame

1 style-matched media element was found among 1 rendered candidates; fill fitting and 0px are the most repeated treatments.

- Role: Visual proof
- Observed instances: 1
  - Fit: `fill`
  - Ratios: `4.77`
  - Radius: `0px`
  - Candidate pool: `1`

### Footer

3 visible actions close the page on a transparent surface.

- Role: Closing navigation
- Observed instances: 1
  - Text: `#f3eee4`
  - Border: `none`
  - Radius: `0px`
  - Padding: `0px 0px 0px 0px`
  - Type: `Helvetica Neue · 16px / 400`
  - Links: `3`

## Imagery

Image led media acts as the page’s primary visual proof rather than decoration. A focused visual anchors the first viewport.

- Inventory: 1 image/canvas element and 0 videos across the analyzed homepage.
- Treatment: fill fitting · square-edged frames

## Motion

10 declared keyframes and 10 active animations were inspectable at capture; observed timing uses 0.16s, 2600ms.

- Libraries: CSS / browser-native or bundled source not identifiable
- Durations: `0.16s`, `2600ms`
- Easings: `ease`, `ease, ease, ease, ease`, `ease, ease, ease`, `cubic-bezier(0.22, 0.61, 0.36, 1)`, `linear`
- Interaction states: hover, focus
- Reduced-motion declaration found: yes

## Responsive behavior

Measured at 390 × 844.

- Desktop navigation reduces from 3 visible actions to 2.
- Hero remains center-aligned; mobile heading size is 14.4px.
- Primary content reads as a single-column mobile flow.
- Horizontal overflow: not detected

## Do

- Pair the observed #0a0c0d canvas with #f3eee4 primary copy before adding secondary surfaces.
- Use Helvetica Neue at 32px/32px, weight 500, for the primary display moment.
- Reserve the strongest first-viewport contrast for “Request data” 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; 50px is the repeated treatment on pills.
- Do not reuse the rgba(243, 238, 228, 0.941) action color across decorative elements; keep its interactive emphasis selective.
- Do not introduce extra type families beyond Helvetica Neue.
- Do not spread the observed shadow treatment across every container; keep elevation selective.

## Evidence

- Hero: `/captures/enact/hero.webp` (960 × 600, scroll 0px) — Visible section: The post-training layer for physical AI.
- Mobile: `/captures/enact/mobile.webp` (390 × 844, scroll 0px) — Visible section: The post-training layer for physical AI.

## Confidence notes

- The hero heading was read from semantic heading markup.
- 1 responsive breakpoint declaration was inspectable.
- 1 stylesheet was 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.
