Design notes

Mood

Serious engineering with editorial confidence — a printing-press serif dropped into a terminal. Quietly premium, deeply dark.

Colors

True black canvas, white type, dim grey secondary text, monochrome trusted-by logo wall; accents rationed to moments: a mint-to-cyan gradient phrase, a purple lens glow, and semantic chips inside mockups (green Delivered, red Bounced, amber Complained).

Type

Massive transitional serif for the hero ('Email for developers') against small clean sans everywhere else; monospace for code with muted syntax colours; centered serif returns for section titles ('Write using a delightful editor').

Layout

Left-anchored serif hero with a dark render bleeding off the top-right → centered monochrome logo wall → glowing icon totem + centered claim → SDK/framework icon row → full-width dark code editor → 2-up product mockup panels, each with a short feature note and 'Learn more' link.

Motion

Slow and reverent: glow pulses on icon totems, gradient shimmer on the accent phrase, the code block types itself in. Nothing playful.

Texture

Matte black with soft volumetric glows; hairline dark borders (#1A1A1A) separate panels; renders are smoky, barely lifted from the void.

Imagery

Subtle 3D renders on black: a barely-lit cube array bleeding off the hero corner, glowing rounded-square app icons (envelope, lens) as section totems, and dark code-editor / email-client mockups. Tool: kie-ai Seedream for the smoky dark renders and glowing icon centerpieces; hand-build code blocks with real syntax colouring. No photography, no bright imagery.

Don't

No white backgrounds, no bright saturated palettes, no bubbly rounded friendliness, no sans-only hero — the serif/black tension IS the brand.

Available licensed assets are used; important UI text is never rendered as a bitmap. - Every visible control has a defined behavior. Loading, empty, error, success, disabled, and long-content states are specified where relevant. Demo data is clearly labeled. - Navigation and content adapt at 375px, 768px, and 1440px without horizontal page overflow. Keyboard use, visible focus, labeled inputs, at least 44px touch targets, readable contrast, and reduced motion are supported. - Verification distinguishes rendered behavior from proposals and identifies anything still requiring a backend or external service. ## Quality bar Clear hierarchy, consistent spacing, restrained surfaces, and purposeful motion. Avoid decorative gradients, excessive cards, placeholder buttons, and invented metrics unless the project calls for them. Do not claim a feature is connected or tested without evidence.
