Design a dark-mode mobile app interface screen: dark editorial luxury framing sculptural sphynx portraits with alternating ivory and obsidian interactive cards.
LAYOUT
A single-column vertical scroll tailored for mobile devices (390px base). The upper viewport is dominated by an immersive hero showcase featuring title typography, subcopy, and progress telemetry. Beneath the hero, content flows through stacked, alternating-tone rounded cards spaced by uniform 14px vertical gaps.
PALETTE (use these exact hex values)
- #0d0f13 — Canvas Obsidian: Root background of the viewport and ambient space behind cards
- #161920 — Card Dark: Background for alternating dark content cards and deep interactive modules
- #f4f3ee — Card Light: High-contrast off-white background for primary feature cards
- #3865ff — Electric Cobalt: Interactive accent for primary pill buttons, active progress indicator, and numeral underlines
- #ffffff — Pure White: Primary display text, hero headline, and status icons over dark surfaces
- #14161b — Deep Charcoal: Headlines and body copy appearing inside light-toned cards
- #7d8494 — Muted Slate: Secondary subtitles, slide total counter, and inactive segment indicators
- #2a2e3b — Subtle Outline: Hairline border for outline pills and dark card contours
TYPOGRAPHY
Typeface Cormorant Garamond (or Playfair Display, Canela, Didot), weights 400/600. Sizes 11px caption, 12px body-sm, 13px body, 15px body-lg, 18px subheading, 26px heading, 44px display. Tracking -0.01em at display, 0.02em at section titles. The typographic tone is regal, editorial, and curated. Cormorant Garamond conveys heritage luxury and high-art sophistication, while Inter provides functional, utilitarian readability for operational details. Any replacement must preserve this tension between classical fine-art serif and modern Swiss sans.
GEOMETRY & SPACING
Corner radii — cards 24px, links 2px, inputs 999px, buttons 999px. Spacing on a 4px unit, 14px gaps, 32px between sections, 390px container, comfortable density.
DEPTH
Depth is created entirely through optical contrast rather than dropped shadows. The intense black background (#0d0f13) recedes infinitely, allowing the luminous bone-white cards (#f4f3ee) to project forward natively while dark cards sit in a mid-plane defined by 1px slate borders (#2a2e3b).
IMAGERY
Studio-lit macro portraits of hairless Sphynx cats captured against seamless dark or light backdrops. Lighting is directional, sculpting the folds of skin and reflective eyes with surgical clarity; casual or outdoor photography would instantly break the gallery elegance.
SIGNATURE DETAIL — the thing that makes this design itself
The alternating rhythm of bone-white and obsidian full-width cards featuring cut-out feline profiles breaking across the typographic grid, unified by electric blue navigational micro-accents.
MUST
- Alternate card background values systematically between ivory (#f4f3ee) and charcoal (#161920).
- Reserve the vivid electric blue (#3865ff) strictly for active states, index accents, and primary actions.
- Pair high-contrast classical serif headings with clean, low-contrast sans-serif body text.
- Isolate feline photography subjects with precise transparent cut-outs that bleed naturally into card boundaries.
AVOID
- Never introduce saturated colors other than the single electric blue (#3865ff) accent token.
- Do not stack two identical light cards immediately adjacent to one another.
- Avoid heavy drop shadows; cards should rely on surface color contrast and crisp borders for separation.
- Never set body paragraphs in the serif font—it must be reserved exclusively for titles and indexes.
