Design a dark-mode mobile app interface screen: deep obsidian surfaces spotlighting tactile 3d clay assets with glowing blue and coral focal points.
LAYOUT
Structured for a narrow single-column mobile viewport. Header utilities anchor the top, followed immediately by a centered hero title, value proposition copy, and CTA button. The body flows into an alternating stack of two-column feature cards where visual illustration tiles and text blocks switch sides row by row, terminating in a centered testimonial block.
PALETTE (use these exact hex values)
- #0B0E14 — Canvas Midnight: Deepest background layer across the entire screen viewport
- #121722 — Card Surface: Background fill for feature sections and testimonial cards
- #0D111A — Card Inner Container: Inset surface framing the 3D illustration tiles within cards
- #4E5EE4 — Electric Indigo: Main primary button background and focal link accents
- #FFFFFF — Text Primary: Used for hero headings, card titles, and high-emphasis labels
- #8C96A5 — Text Muted: Subheadlines, paragraph descriptions, and author attribution roles
- #E05A67 — Coral Accent: Numerical badge highlights, metric stats, and callout numbers
- #1EB980 — Emerald Accent: Secondary step badge indicator and growth metric accents
- #282B46 — Violet Tint: Subtle low-contrast pill badge background for step 01
TYPOGRAPHY
Typeface Inter (or Plus Jakarta Sans,SF Pro Display,DM Sans), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 14px body, 15px body-lg, 17px subheading, 20px heading, 32px display. Tracking -0.02em at display, 0 at body. Clean, highly modern, and authoritative sans-serif typography that communicates premium quality through precise geometric forms. Tight negative tracking on large titles creates impact while generous line heights on body paragraphs preserve legibility on dark backgrounds. Inter or Plus Jakarta Sans are optimal matches.
GEOMETRY & SPACING
Corner radii — cards 16px, links 4px, inputs 12px, buttons 12px. Spacing on a 8px unit, 16px gaps, 48px between sections, 390px container, comfortable density.
DEPTH
Depth is created purely through nuanced shifts in surface darkness rather than dropped blur shadows. Elements step upward from the #0B0E14 background canvas to #121722 card containers, accented by deeply recessed inset illustration panels at #0D111A. Subtle rim-lighting on 3D isometric models provides organic depth without requiring synthetic CSS shadows.
IMAGERY
Features bespoke isometric 3D clay-render models (piggy bank with gold coins, forklift with cargo blocks, director's chair with spotlight) with soft matte textures and minimal specular highlights. Elements use a primarily neutral grey-white palette with single-color accents (green plant, blue boxes, pink megaphones). Photorealistic, glossy, or flat 2D vector illustrations are completely off-brand.
SIGNATURE DETAIL — the thing that makes this design itself
The two-column feature card containing a square-proportioned dark inset tile holding a matte isometric 3D object, paired opposite a sequence badge and concise copy. Removing this modular card structure and replacing the 3D clay visuals with flat iconography would destroy the identity completely. Commonly misused by making the 3D models hyper-glossy or breaking the clean alternating left/right layout.
MUST
- Use solid 16px corner radiuses on all card enclosures and container wrappers.
- Alternate the position of 3D artwork (left-right-left) to maintain visual rhythm across list items.
- Highlight specific metrics or quantities inside body text using brand accent colors (#4E5EE4, #E05A67).
- Keep card surface tones very close to the background canvas tone to preserve deep atmospheric depth.
AVOID
- Never apply harsh white borders or high-opacity outlines around cards or buttons.
- Do not use glossy or metallic materials on 3D elements; stick strictly to clay-like matte finishes.
- Avoid centering body text inside feature split cards; keep all content left-aligned under the step badge.
- Never use pure black (#000000) for the background; maintain the deep navy-tinted charcoal (#0B0E14).
