Design a light-mode mobile app interface screen: precision automotive engineering framed in deep spruce tones, crisp daylight surfaces, and technical geometric typography.
LAYOUT
The screen follows a strict single-column mobile flow with modular rhythm: top status bar and minimalist brand selector header (48px), followed by a dominant full-bleed dark showcase banner (~340px). Below rests a 5-item horizontal feature icon bar, leading into a bold uppercase section title ('NỔI BẬT') and a rigorous 2-column card grid with 12px gaps.
PALETTE (use these exact hex values)
- #FFFFFF — Canvas White: Global application background and crisp foreground card highlight surface.
- #0B2D33 — Spruce Deep: Dominant dark hero card backdrop evoking automotive paint depth.
- #041B20 — Spruce Abyss: Gradient anchor for the dark showcase banner floor.
- #103238 — Ink Spruce: Primary typography, titles, icons, and prominent headers across daylight surfaces.
- #5D7179 — Slate Muted: Secondary product descriptions, subtitles, and icon labels.
- #F2F5F8 — Ice Fog: Subtle cool-tinted fill for product feature cards and icon circles.
- #E3EBF0 — Ghost Spruce: Ultra-light hairline borders on category icon circles and dividers.
- #E53935 — Signal Crimson: High-visibility dot indicator on notification icon in the header.
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, Montserrat, SF Pro Text), weights 400/500/600/700/800. Sizes 11px caption, 13px body-sm, 14px body, 15px subheading, 17px heading, 26px display. Tracking -0.01em at display, 0.02em at uppercase captions. Plus Jakarta Sans delivers a disciplined, engineered, and modern automotive feel. High-contrast uppercase headings communicate power and precision without shouting, while compact body copy maintains high legibility even in Vietnamese diacritics. Inter or SF Pro Display make seamless drop-in alternatives without losing technical authority.
GEOMETRY & SPACING
Corner radii — cards 18px, links 4px, inputs 12px, buttons 999px. Spacing on a 4px unit, 12px gaps, 28px between sections, 390px container, comfortable density.
DEPTH
Depth is created purely through ambient photographic drop shadows cast by the vehicles onto card floors, rather than CSS box-shadows. The interface remains intentionally flat and crisp, using 1px boundary borders (#E3EBF0) and tonal surface changes (#FFFFFF to #F2F5F8) to segment hierarchical planes.
IMAGERY
Imagery features studio-lit automotive exterior and interior studio shots cut out against gradients or environmental city backdrops. Vehicle reflections must echo the spruce and cool-teal palette, emphasizing sleek metallic surfaces, polished alloy wheels, and pristine interior leather dashboard angles.
SIGNATURE DETAIL — the thing that makes this design itself
The dramatic transition from a deep nocturnal spruce-green hero banner down to clinical, daylight-bright feature cards with fine circular wireframe action nodes.
MUST
- Use uppercase lettering for all high-level category titles and card headlines to maintain architectural punch.
- Restrict the deep spruce green palette to hero elements, car paint reflections, and key text headings.
- Maintain consistent 18px rounded corners across all secondary showcase cards.
- Isolate car photography cleanly with soft cast shadows rather than heavy drop shadows.
AVOID
- Do not use harsh pure black (#000000); use Spruce Deep (#103238) for deep contrast.
- Never add solid colored button backgrounds in the hero; keep the ghost outline aesthetic.
- Avoid flat rectangle cards; sharp 0px corners completely violate this system's smooth ergonomic language.
- Do not clutter secondary feature cards with complex badges or multiple call-to-actions.
