## Visual thesis

Light, left-aligned split product story with sharp geometry and image-led proof.

Hilstart opens with “Hardware development, on autopilot.” in a left-aligned split hero. The homepage continues through 8 observed sections, moving from the opening proposition into Agent driven, human verifiable, The hardware interface, Run it in our cloud, or from your own environment.

## Color

Light surfaces use 7 repeated semantic colors; hierarchy is carried mainly by tonal contrast.

| Token | Value | Role | Usage |
| --- | --- | --- | --- |
| Canvas | `#f6f5f0` | Page canvas | Dominant rendered page background. |
| Surface 1 | `#efece4` | Surface | Repeated container or section fill; relative occurrence score 154. |
| Surface 2 | `#0e0f10` | Surface | Repeated container or section fill; relative occurrence score 150. |
| Surface 3 | `#e5e1d6` | Surface | Repeated container or section fill; relative occurrence score 100. |
| Primary text | `#0e0f10` | Primary text | Observed display foreground with 17.6:1 contrast against the captured canvas. |
| Secondary text | `rgba(14, 15, 15, 0.78)` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 9.2:1. |
| Border | `rgba(14, 14, 14, 0.141)` | Border and divider | Most repeated inspectable border color. |

## Typography

The observed type system assigns Hanken Grotesk to display, heading, body text; JetBrains Mono to body-small, label text.

| Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| display | Hanken Grotesk | 78px | 500 | 81.12px | -2.34px | normal | none | rgb(14, 15, 16) |
| heading | Hanken Grotesk | 54px | 500 | 54px | -1.89px | normal | none | rgb(246, 245, 241) |
| body | Hanken Grotesk | 18px | 400 | 27.9px | 0px | normal | none | rgb(14, 15, 16) |
| body-small | JetBrains Mono | 10.5px | 400 | 15.75px | 1.47px | normal | none | rgb(15, 107, 48) |
| label | JetBrains Mono | 11px | 400 | 16.5px | 1.1px | normal | none | rgba(13, 15, 17, 0.600) |

## Spacing and shape

- Base unit: 4px

- Shadows: `rgba(22, 163, 74, 0.32) 0px 0px 0px 1px`

## Layout

- Macrostructure: Split product narrative
- Hero: Split hero: message and proof share the first viewport
- Grid: 2 columns
- Footer: Utility footer with 7 actions
- Reading flow: The homepage continues through 8 observed sections, moving from the opening proposition into Agent driven, human verifiable, The hardware interface, Run it in our cloud, or from your own environment.
- Section sequence: Agent driven, human verifiable. → The hardware interface. → Run it in our cloud, or from your own environment. → Will this work for my setup? → Close the loop on your hardware. → Single source of truth. → Generate hardware tests. → Run tests on real hardware.

## Imagery

Image led media acts as the page’s primary visual proof rather than decoration. Multiple visual elements share the first viewport.

- Inventory: 6 images/canvas elements and 0 videos across the analyzed homepage.
- Treatment: fill fitting · square-edged frames

## Motion

1 declared keyframe and 1 active animation were inspectable at capture; observed timing uses 0.2s, 2s, 0.15s.

- Libraries: CSS / browser-native or bundled source not identifiable
- Durations: `0.2s`, `2s`, `0.15s`
- Easings: `ease`, `ease, ease`, `ease, ease, ease, ease`, `linear`
- Interaction states: hover, focus
- Reduced-motion declaration found: yes

## Responsive behavior

Measured at 390 × 844.

- Desktop navigation reduces from 6 visible actions to 1.
- Hero alignment changes from left to center; mobile heading size is 32.064px.
- 1 multi-column content region remains on mobile.
- Horizontal overflow: not detected

## Do

- Pair the observed #f6f5f0 canvas with #0e0f10 primary copy before adding secondary surfaces.
- Use Hanken Grotesk at 78px/81.12px, weight 500, for the primary display moment.
- Let the left-aligned split hero establish hierarchy before secondary content.
- Image led media acts as the page’s primary visual proof rather than decoration.

## Don’t

- Do not mix in arbitrary radii; 2px is the repeated treatment on containers.
- Do not introduce an accent hue that is absent from the captured palette.
- Do not introduce extra type families beyond Hanken Grotesk and JetBrains Mono.
- Do not spread the observed shadow treatment across every container; keep elevation selective.

## Evidence

- Hero: `/captures/hilstart/hero.webp` (960 × 600, scroll 0px) — Visible section: Hardware development, on autopilot.
- Mid-page: `/captures/hilstart/middle.webp` (960 × 600, scroll 2738px) — Visible section: The hardware interface.
- Closing: `/captures/hilstart/closing.webp` (960 × 600, scroll 5256px) — Visible section: Close the loop on your hardware.
- Mobile: `/captures/hilstart/mobile.webp` (390 × 844, scroll 0px) — Visible section: Hardware development, on autopilot.

## Confidence notes

- The hero heading was read from semantic heading markup.
- 11 responsive breakpoint declarations were inspectable.
- 12 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.
