Design a light-mode mobile app interface screen: moody warehouse cinema meets crisp editorial card architecture for gritty urban action sports.
LAYOUT
The viewport begins with a full-bleed dark hero photography header occupying approximately 42% of the screen height, featuring top navigation icons, oversized display type, and CTA. The content layer transitions via a heavy 24px top-rounded white sheet containing section header rows with 'See all' links. Below, horizontal media carousels, progress trackers, and editorial promo cards stack vertically with consistent 16px gutters.
PALETTE (use these exact hex values)
- #F8F9FA — Base Sheet: Background canvas for the sliding content bottom sheet and list sections
- #0D1117 — Dark Hero Base: Dark moody base beneath hero video backdrop and media card containers
- #22808D — Teal Brand: Primary action buttons, active slider dots, badge fills, and progress bars
- #1E4F57 — Deep Teal Slate: Progress icon badge base and secondary graphic accents
- #EBF2F2 — Card Soft Neutral: Background fill for challenge progress card and muted utility containers
- #121417 — Text Primary Dark: Primary headings, titles, and section markers on light surfaces
- #6C757D — Text Secondary Muted: Subtitles, metadata, timestamps, and secondary captions
- #FFFFFF — Pure White: Display text and controls placed over dark hero and video imagery
TYPOGRAPHY
Typeface Bebas Neue (or Oswald,Barlow Condensed,Impact), weights 700/900. Sizes 11px caption, 13px body-sm, 15px body, 17px subheading, 20px heading, 28px heading-lg, 52px display. Tracking 0.02em to 0.05em. The typography presents a bold, rebellious, yet premium athletic voice. The towering condensed display font communicates raw momentum, physical grit, and urban attitude reminiscent of independent zines and skate cinema. Pairing it with a neutral, geometric sans serif grounds the UI, ensuring that functional navigation remains instantly legible.
GEOMETRY & SPACING
Corner radii — cards 20px, links 999px, inputs 12px, buttons 12px. Spacing on a 4px unit, 16px gaps, 24px between sections, 390px container, comfortable density.
DEPTH
Depth is created strictly through visual layering rather than traditional drop shadows. The curved light sheet (#F8F9FA) sits physically over the edge of the hero photography canvas, creating an architectural overlap. Media controls use translucent glass blurs that float immediately over the video stills.
IMAGERY
Cinematic, urban, and industrial action-sports photography dominates the visual space. Stills feature moody warehouse interiors, desaturated tones, natural dramatic lighting, and deep shadows with high local contrast. Avoid glossy commercial studio portraits or overly saturated outdoor beach/skate photography.
SIGNATURE DETAIL — the thing that makes this design itself
The theatrical transition from the full-bleed dark industrial hero image directly into an overlapping rounded light content sheet. This gives the app a dynamic cinematic-to-editorial shift that prevents the dark streaming aesthetic from feeling oppressive.
MUST
- Use Bebas Neue or a tight ultra-condensed font exclusively for primary high-energy headings.
- Round all featured cards and bottom sheets to exactly 20px for modern organic corner flow.
- Restrict the teal accent (#22808D) to active statuses, play buttons, and critical highlights.
- Ensure video cards have dark gradient overlays at the foot to keep white typography legible.
AVOID
- Never use condensed display typography for body text, descriptions, or utility labels.
- Do not use sharp 0px or small 4px border radii; cards must maintain 16px to 20px curves.
- Avoid multi-colored accents; do not mix teal with red, yellow, or bright green.
- Do not drop full-color saturated imagery into the cards without checking text contrast.
