## Visual thesis

Dark, left-aligned type-led product story with rounded geometry and restrained visual proof.

TareBio \| Vaccines for any cancer or infection opens with “TareBio” in a left-aligned type-led hero. The experience remains a single composed scene rather than a multi-section narrative.

## Color

Dark surfaces use 3 repeated semantic colors; hierarchy is carried mainly by tonal contrast.

| Token | Value | Role | Usage |
| --- | --- | --- | --- |
| Canvas | `#27243d` | Page canvas | Dominant rendered page background. |
| Primary text | `#efedfb` | Primary text | Observed display foreground with 12.9:1 contrast against the captured canvas. |
| Secondary text | `#ed6d2d` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 4.9:1. |

## Typography

The observed type system assigns Newsreader Variable to display, body text; Inter Variable to label text.

| Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| display | Newsreader Variable | 72px | 550 | 72px | -1.44px | normal | none | rgb(239, 237, 251) |
| body | Newsreader Variable | 28px | 420 | 36.4px | -0.28px | normal | none | rgb(237, 109, 45) |
| label | Inter Variable | 17px | 400 | normal | 0px | normal | none | rgb(157, 153, 196) |

## Spacing and shape

- Base unit: 4px
- Density: sparse
- Maximum content width: 1152px
- Section gap: 48px
- Container padding: 20px
- Common spacing: `48px`, `80px`, `20px`, `36px`
- Corner strategy: Rounded geometry is the dominant shape voice. Separation relies on borders and surface contrast rather than shadow.
- Radii: Containers `50px`
- Borders: `No repeated border treatment detected`
- Shadows: `None observed`

## Layout

- Macrostructure: Single-scene landing
- Hero: Type-led hero: display copy is the primary graphic
- Grid: Single-column flow
- Footer: No footer detected
- 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

Type led, left-aligned opening anchored by the primary message.

- Role: Opening proposition
- Observed instances: 1
  - Pattern: `type-led`
  - Alignment: `left`
  - Heading: `Newsreader Variable · 72px / 550`
  - Media: `minimal`

## Imagery

Typography and surface contrast carry the page; rendered imagery is minimal. The first viewport is type-led.

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

## Motion

3 declared keyframes and 5 active animations were inspectable at capture; observed timing uses 22s, 28s, 0.6s.

- Libraries: CSS / browser-native or bundled source not identifiable
- Durations: `22s`, `28s`, `0.6s`, `22000ms`, `28000ms`, `600ms`
- Easings: `ease-in-out`, `ease, ease`, `cubic-bezier(0.2, 0.7, 0.3, 1)`, `linear`
- Interaction states: focus, hover
- Reduced-motion declaration found: yes

## Responsive behavior

Measured at 390 × 844.

- The same 0 visible navigation actions remain at mobile width.
- Hero alignment changes from left to center; mobile heading size is 48px.
- Primary content reads as a single-column mobile flow.
- Horizontal overflow: not detected

## Do

- Pair the observed #27243d canvas with #efedfb primary copy before adding secondary surfaces.
- Use Newsreader Variable at 72px/72px, weight 550, for the primary display moment.
- Let the left-aligned type-led hero establish hierarchy before secondary content.
- Typography and surface contrast carry the page; rendered imagery is minimal.

## Don’t

- Do not mix in arbitrary radii; 50px 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 Newsreader Variable and Inter Variable.
- Do not add card shadows; the source separates content without repeated elevation.

## Evidence

- Hero: `/captures/tarebio/hero.webp` (960 × 600, scroll 0px) — Visible section: TareBio
- Mobile: `/captures/tarebio/mobile.webp` (390 × 844, scroll 0px) — Visible section: TareBio

## Confidence notes

- The hero heading was read from semantic heading markup.
- No same-origin breakpoint declarations were inspectable; mobile behavior was measured directly.
- 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.
