Tenor \| Build AI-native service businesses opens with “The infrastructure for the next generation of businesses built around AI.” in a center-aligned stacked hero. The homepage continues through 8 observed sections, moving from the opening proposition into Context. Work. Control. Learning, Every outcome improves what happens next, The system learns what to do next. ## Color Light surfaces use 8 repeated semantic colors; the primary action carries the strongest interactive emphasis. | Token | Value | Role | Usage | | --- | --- | --- | --- | | Canvas | `#f7f5f1` | Page canvas | Dominant rendered page background. | | Surface 1 | `#f7f6f2` | Surface | Repeated container or section fill; relative occurrence score 240. | | Surface 2 | `#10100f` | Surface | Repeated container or section fill; relative occurrence score 127. | | Surface 3 | `#eeece6` | Surface | Repeated container or section fill; relative occurrence score 91. | | Primary text | `#8f8e89` | Primary text | Observed display foreground; its canvas-reference contrast is 3.0:1 and may rely on a local hero surface. | | Secondary text | `rgba(16, 16, 15, 0.741)` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 8.0:1. | | Action | `#10100f` | Primary action | Fill used by the dominant first-viewport action. | | Border | `rgba(19, 19, 12, 0.161)` | Border and divider | Most repeated inspectable border color. | ## Typography The observed type system assigns Instrument Sans to display, heading, body text; IBM Plex Mono to body-small, label text. | Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color | | --- | --- | --- | --- | --- | --- | --- | --- | --- | | display | Instrument Sans | 67.2px | 400 | 61.152px | -4.368px | normal | none | rgb(143, 142, 137) | | heading | Instrument Sans | 92.8px | 400 | 94.656px | -6.032px | normal | none | rgb(247, 246, 242) | | body | Instrument Sans | 18.88px | 400 | 28.32px | -0.3776px | normal | none | rgba(16, 16, 15, 0.741) | | body-small | IBM Plex Mono | 10.24px | 500 | 12.8px | 0.9216px | normal | none | rgb(111, 111, 107) | | label | IBM Plex Mono | 9.92px | 500 | 9.92px | 0.7936px | normal | none | rgb(111, 111, 107) | ## Spacing and shape - Base unit: 4px - Density: sparse - Maximum content width: 1312px - Section gap: 52px - Container padding: 24px - Common spacing: `10px`, `24px`, `8px`, `28px`, `12px`, `52px`, `48px`, `64px`, `7px`, `18px` - Corner strategy: Sharp geometry is the dominant shape voice. Separation relies on borders and surface contrast rather than shadow. - Radii: Media `0px` - Borders: `1px solid rgba(19, 19, 12, 0.161)`, `1px solid rgba(245, 245, 240, 0.200)` - Shadows: `None observed` ## Layout - Macrostructure: Stacked product narrative - Hero: Stacked hero: message leads into visual proof within the opening - Grid: 1 column - Footer: Utility footer with 6 actions - Reading flow: The homepage continues through 8 observed sections, moving from the opening proposition into Context. Work. Control. Learning, Every outcome improves what happens next, The system learns what to do next. - Section sequence: Context. Work. Control. Learning. → Every outcome improves what happens next. → The system learns what to do next. → Build your company around AI. → Company data layer → Reason Create Act → Harness + workflows → Checkpoints + controls ## Component grammar ### Hero Stacked, center-aligned opening anchored by “Request access ↗”. - Role: Opening proposition - Observed instances: 1 - Pattern: `stacked` - Alignment: `center` - Heading: `Instrument Sans · 67.2px / 400` - Media: `image-led` ### Navigation Static navigation with 5 visible actions in the desktop opening. - Role: Global wayfinding - Observed instances: 1 - Text: `#10100f` - Border: `none` - Radius: `0px` - Padding: `0px 0px 0px 0px` - Type: `Instrument Sans · 16px / 400` - Position: `static` - Height: `31px` ### Primary action “Request access ↗” is the strongest first-viewport action by semantic intent and visual contrast. - Role: Conversion - Observed instances: 1 - Background: `#10100f` - Text: `#f7f6f2` - Border: `none` - Radius: `0px` - Padding: `0px 20px 0px 20px` - Type: `IBM Plex Mono · 10.88px / 500` ### Media frame 2 style-matched media elements were found among 4 rendered candidates; fill fitting and 0px are the most repeated treatments. - Role: Visual proof - Observed instances: 2 - Fit: `fill` - Ratios: `1.88, 2.78, 1.21` - Radius: `0px` - Candidate pool: `4` ### Footer 6 visible actions close the page on a #10100f surface. - Role: Closing navigation - Observed instances: 1 - Background: `#10100f` - Text: `#f7f6f2` - Border: `none` - Radius: `0px` - Padding: `72px 0px 28px 0px` - Type: `Instrument Sans · 16px / 400` - Links: `6` ## 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 0 videos across the analyzed homepage. - Treatment: fill fitting · square-edged frames ## Motion 0 declared keyframes and 2 active animations were inspectable at capture; observed timing uses 180ms, 260ms, 0.01ms. - Libraries: CSS / browser-native or bundled source not identifiable - Durations: `180ms`, `260ms`, `0.01ms`, `820ms` - Easings: `ease, ease`, `ease`, `cubic-bezier(0.22, 1, 0.36, 1), cubic-bezier(0.22, 1, 0.36, 1)`, `cubic-bezier(0.22, 1, 0.36, 1)`, `ease, ease, ease` - Interaction states: focus, hover - Reduced-motion declaration found: yes ## Responsive behavior Measured at 390 × 844. - Desktop navigation reduces from 5 visible actions to 3. - Hero remains center-aligned; mobile heading size is 33.15px. - 8 multi-column content regions remain on mobile. - Horizontal overflow: not detected ## Do - Pair the observed #f7f5f1 canvas with #8f8e89 primary copy before adding secondary surfaces. - Use Instrument Sans at 67.2px/61.152px, weight 400, for the primary display moment. - Reserve the strongest first-viewport contrast for “Request access ↗” 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; 0px is the repeated treatment on media. - Do not reuse the #10100f action color across decorative elements; keep its interactive emphasis selective. - Do not introduce extra type families beyond Instrument Sans and IBM Plex Mono. - Do not add card shadows; the source separates content without repeated elevation. ## Evidence - Hero: `/captures/tenor/hero.webp` (960 × 600, scroll 0px) — Visible section: The infrastructure for the next generation of businesses built around AI. - Mid-page: `/captures/tenor/middle.webp` (960 × 600, scroll 2345px) — Visible section: Checkpoints + controls · Every outcome improves what happens next. - Closing: `/captures/tenor/closing.webp` (960 × 600, scroll 4470px) — Visible section: Build your company around AI. - Mobile: `/captures/tenor/mobile.webp` (390 × 844, scroll 0px) — Visible section: The infrastructure for the next generation of businesses built around AI. ## Confidence notes - The hero heading was read from semantic heading markup. - 5 responsive breakpoint declarations were inspectable. - 1 stylesheet was inspectable; 1 cross-origin stylesheet was unavailable to rule inspection. - Computed styles describe the captured render; source design tokens and proprietary font files were not copied.
