Design a dark-mode mobile app interface screen: stealth dark-mode outdoor commerce illuminated by neon cyan telemetry accents and tactical pill containers.
LAYOUT
Vertical single-column scroll optimized for mobile viewport thumb zones. Top-to-bottom sequence flows from navigation and product hero stage, down to title/pricing lockup, followed by horizontal 4-pack specs, narrative intro, 2-column benefits matrix, and dual selector cards. The experience terminates in a persistent fixed bottom pill button for effortless one-tap checkout.
PALETTE (use these exact hex values)
- #0D1117 — Obsidian Deep: Root background canvas framing the product display and body content
- #141D26 — Graphite Card: Container background for spec grids, benefits, and attribute selectors
- #212F3D — Subtle Border: Hairline card boundaries and active color swatch ring indicators
- #30C7B5 — Teal Electric: Primary CTA button background, success checkmarks, shipping badges, and active dots
- #FFFFFF — Optic White: Product headline, price, button label, and primary specification text
- #8A9BA8 — Cool Slate: Subtitles, secondary body copy, spec definitions, and inactive controls
- #485968 — Dim Slate: Inactive carousel indicators, disabled text, and minor divider lines
- #E83A7E — Product Hot Pink: Active color swatch matching the ski goggle frame in the viewport
TYPOGRAPHY
Typeface SF Pro Display (or Inter,Plus Jakarta Sans,Roboto), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 14px body, 14px subheading, 16px body-lg, 28px heading, 32px display. Tracking -0.03em at display, 0.05em at uppercase caption. Industrial, technical, and athletic without feeling aggressive. The clean grotesque sans-serif delivers high-readability telemetry through wide letter-spacing on micro-captions and bold condensed impact on model names. Inter or SF Pro Display works seamlessly without proprietary dependencies.
GEOMETRY & SPACING
Corner radii — cards 16px, links 8px, inputs 24px, buttons 999px. Spacing on a 4px unit, 16px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth relies strictly on atmospheric surface value increments rather than cast drop shadows. Level 0 canvas is near-black (#0D1117), rising to Level 1 cards (#141D26) defined by a 1px border (#212F3D). The only luminous elevation is the product reflection and the subtle emissive glow from the solid teal CTA button.
IMAGERY
Photorealistic 3D hardware rendering with physical material properties, studio backlighting, and crisp horizon reflections. The product floats isolated on a dark matte floor without scenic outdoor clutter. Showing flat 2D vector illustrations or low-contrast washed-out lifestyle photos would violate the aesthetic.
SIGNATURE DETAIL — the thing that makes this design itself
The signature element is the horizontal spec capsule: a single 16px radius dark card segmented into balanced technical icon cells with two-line uppercase micro-typography. This communicates outdoor ruggedness and aerospace-grade spec sheets in a compact mobile footprint. Misusing it means bloating the cells with long sentences or removing icon parity.
MUST
- Keep all spec tags and benefit category labels in strict uppercase tracking (0.8px to 1.2px).
- Use solid 1px borders (#212F3D) on dark cards to separate them cleanly from the canvas.
- Limit electric teal (#30C7B5) strictly to checkout affordances, active pagination, and positive badges.
- Align title and price baseline symmetrically across the horizontal screen axis.
AVOID
- Never introduce standard pure-black (#000000) cards; always use blue-tinted dark slate (#141D26).
- Avoid using drop shadows on cards; use border strokes (#212F3D) to define depth.
- Do not style secondary or inactive buttons with bright teal accents.
- Never display body text in full 100% white; mute it to cool slate (#8A9BA8) to preserve hierarchy.
