## Visual thesis

Light, left-aligned split product story with soft geometry and video-led proof.

Aerogen Systems · Point-of-use contamination control opens with “Fabs of the future.” in a left-aligned split hero. The homepage continues through 9 observed sections, moving from the opening proposition into Every defect has a cost, Meet Talos, Clean room Pipes.

## Color

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

| Token | Value | Role | Usage |
| --- | --- | --- | --- |
| Canvas | `#fffaf7` | Page canvas | Dominant rendered page background. |
| Surface 1 | `#00162c` | Surface | Repeated container or section fill; relative occurrence score 114. |
| Surface 2 | `#bcdce5` | Surface | Repeated container or section fill; relative occurrence score 96. |
| Surface 3 | `#0090b9` | Surface | Repeated container or section fill; relative occurrence score 46. |
| Primary text | `#00162c` | Primary text | Observed display foreground with 17.6:1 contrast against the captured canvas. |
| Secondary text | `rgba(0, 22, 44, 0.8)` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 9.7:1. |
| Action | `#0090b9` | Primary action | Fill used by the dominant first-viewport action. |
| Border | `#dbdadb` | Border and divider | Most repeated inspectable border color. |

## Typography

The observed type system assigns Playfair Display to display, heading text; Montserrat to body, body-small text; JetBrains Mono to label text.

| Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| display | Playfair Display | 67.2px | 500 | 70.56px | -1.008px | normal | none | rgb(0, 22, 44) |
| heading | Playfair Display | 54.4px | 500 | 58.752px | -0.816px | normal | none | rgb(0, 22, 44) |
| body | Montserrat | 15.5px | 400 | 25.1875px | 0px | normal | none | rgba(0, 22, 44, 0.800) |
| body-small | Montserrat | 14px | 400 | 22.75px | 0px | normal | none | rgb(100, 91, 75) |
| label | JetBrains Mono | 12.5px | 400 | 18.75px | 0px | normal | none | rgb(0, 22, 44) |

## Spacing and shape

- Base unit: 4px
- Density: sparse

- Common spacing: `24px`, `28px`, `20px`, `96px`, `16px`, `56px`, `12px`, `8px`, `4px`, `40px`
- Corner strategy: Soft geometry is the dominant shape voice. Elevation is selectively reinforced with shadow.
- Radii: Media `6px`, Pills `9999px`, Containers `6px`, Buttons `0px`

- Shadows: `rgba(0, 22, 44, 0.12) 0px 4px 16px -6px`, `rgba(0, 22, 44, 0.14) 0px 6px 18px -4px`, `rgba(0, 22, 44, 0.2) 0px 16px 40px -8px`, `rgba(0, 22, 44, 0.68) 0px 20px 44px -14px`

## Layout

- Macrostructure: Split product narrative
- Hero: Split hero: message and proof share the first viewport
- Grid: 2 columns
- Footer: Utility footer with 5 actions
- Reading flow: The homepage continues through 9 observed sections, moving from the opening proposition into Every defect has a cost, Meet Talos, Clean room Pipes.
- Section sequence: Every defect has a cost. → Meet Talos. → Clean room Pipes. → A pilot, not a pitch. → The future of contamination control in semiconductor manufacturing. → Facing yield problems? We'll build a system to fix it. → Discussion → Evaluation → Integration

## Component grammar

### Hero

Split, left-aligned opening anchored by “Join the Pilot Program”.

- Role: Opening proposition
- Observed instances: 1
  - Pattern: `split`
  - Alignment: `left`
  - Heading: `Playfair Display · 67.2px / 500`
  - Media: `video-led`

### Navigation

Static navigation with 6 visible actions in the desktop opening.

- Role: Global wayfinding
- Observed instances: 1
  - Text: `#281d08`
  - Border: `none`
  - Radius: `0px`
  - Padding: `0px 0px 0px 0px`
  - Type: `Montserrat · 16px / 400`
  - Position: `static`
  - Height: `20px`

### Primary action

“Join the Pilot Program” is the strongest first-viewport action by semantic intent and visual contrast.

- Role: Conversion
- Observed instances: 1
  - Background: `#0090b9`
  - Text: `#fffaf7`
  - Border: `none`
  - Radius: `9999px`
  - Padding: `12px 28px 12px 28px`
  - Type: `Montserrat · 14.5px / 500`

### Media frame

6 style-matched media elements were found among 11 rendered candidates; contain fitting and 6px are the most repeated treatments.

- Role: Visual proof
- Observed instances: 6
  - Fit: `contain, fill, cover`
  - Ratios: `1.00, 3.24, 1.40, 1.78, 3.20`
  - Radius: `6px, 0px`
  - Candidate pool: `11`

### Footer

5 visible actions close the page on a #bcdce5 surface.

- Role: Closing navigation
- Observed instances: 1
  - Background: `#bcdce5`
  - Text: `#281d08`
  - Border: `none`
  - Radius: `0px`
  - Padding: `0px 0px 0px 0px`
  - Type: `Montserrat · 16px / 400`
  - Links: `5`

## Imagery

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

- Inventory: 9 images/canvas elements and 2 videos across the analyzed homepage.
- Treatment: contain fitting · 6px repeated radius

## Motion

2 declared keyframes and 4 active animations were inspectable at capture; observed timing uses 0.1s, 0.2s, 0.3s.

- Libraries: CSS / browser-native or bundled source not identifiable
- Durations: `0.1s`, `0.2s`, `0.3s`, `0.7s`, `700ms`
- Easings: `ease`, `cubic-bezier(0, 0, 0.2, 1)`
- Interaction states: focus, transition-all, hover, active, disabled
- Reduced-motion declaration found: yes

## Responsive behavior

Measured at 390 × 844.

- Desktop navigation reduces from 6 visible actions to 2.
- Hero alignment changes from left to center; mobile heading size is 48px.
- Observed multi-column desktop regions collapse to a single-column mobile flow.
- Horizontal overflow: detected

## Do

- Pair the observed #fffaf7 canvas with #00162c primary copy before adding secondary surfaces.
- Use Playfair Display at 67.2px/70.56px, weight 500, for the primary display moment.
- Reserve the strongest first-viewport contrast for “Join the Pilot Program” within the left-aligned split hero.
- Video led media acts as the page’s primary visual proof rather than decoration.

## Don’t

- Do not mix in arbitrary radii; 6px is the repeated treatment on media.
- Do not reuse the #0090b9 action color across decorative elements; keep its interactive emphasis selective.
- Do not introduce extra type families beyond Playfair Display and Montserrat and JetBrains Mono.
- Do not copy transition-all declarations; keep only purposeful transform or opacity motion.

## Evidence

- Hero: `/captures/aerogen-systems/hero.webp` (960 × 600, scroll 0px) — Visible section: Fabs of the future. · Every defect has a cost.
- Mid-page: `/captures/aerogen-systems/middle.webp` (960 × 600, scroll 2213px) — Visible section: Clean room Pipes. · A pilot, not a pitch.
- Closing: `/captures/aerogen-systems/closing.webp` (960 × 600, scroll 4206px) — Visible section: Facing yield problems? We'll build a system to fix it.
- Mobile: `/captures/aerogen-systems/mobile.webp` (390 × 844, scroll 0px) — Visible section: Fabs of the future.

## Confidence notes

- The hero heading was read from semantic heading markup.
- 3 responsive breakpoint declarations were 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.
