Design a light-mode web interface screen: tactile courier operations balanced between warm linen surfaces and clean isometric clay narratives.
LAYOUT
The screen follows an asymmetric master-detail layout: a narrow fixed vertical rail on the far left, followed by a primary fluid canvas with a top-anchored header row. The hero section divides into a left-aligned headline with action buttons and a sweeping right-side isometric journey path illustration. Beneath, four equally weighted service cards span the horizontal axis, anchored at the bottom by a unified four-column KPI metrics container.
PALETTE (use these exact hex values)
- #FAF8F5 — Canvas Linen: Main backdrop canvas behind hero, cards, and primary content areas.
- #161922 — Sidebar Obsidian: Vertical rail navigation background providing deep structural contrast.
- #FFFFFF — Card Pure White: Foreground surface for service cards, metric wrappers, and popup elements.
- #C84C3E — Terracotta Brand: Primary actions, key CTA buttons, active indicators, and thematic accents.
- #FBEBE8 — Terracotta Soft: Subtle badge fills, illustration wash backdrops, and active menu highlights.
- #11141A — Text Primary: Display headlines, prominent card titles, and primary stat values.
- #727682 — Text Secondary: Explanatory body copy, sub-labels, and idle sidebar iconography.
- #EDE8DF — Card Border Linen: Subtle bounding line for cards, stats container, and secondary buttons.
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, DM Sans, Outfit), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 14px body, 16px body-lg, 20px subheading, 28px heading, 44px display. Tracking -0.03em on headlines, 0em on body. Plus Jakarta Sans delivers a brisk, European industrial precision that balances warm geometry with operational clarity. The heavy weight at 44px on headlines communicates dependable logistics infrastructure, while tabular numerals ensure metrics align effortlessly. Clean freely available alternatives like Inter or DM Sans retain the intended tone without friction.
GEOMETRY & SPACING
Corner radii — cards 20px, links 999px, inputs 10px, buttons 10px. Spacing on a 4px unit, 20px gaps, 64px between sections, 1440px container, comfortable density.
DEPTH
Depth is handled almost entirely through deliberate surface planes and extremely soft, diffuse ambient contact occlusion beneath 3D models. Cards sit flush against the linen canvas with a crisp 1px neutral border (#EDE8DF) rather than prominent drop shadows. The dark sidebar acts as a deep planar anchor, establishing immediate foreground separation.
IMAGERY
Visual assets consist strictly of warm, minimalist 3D isometric clay-style renders with smooth surfaces, matte textures, and soft directional shadows. Depicted subjects are modern transport and logistics motifs: drones carrying parcels, courier vans, electric mopeds, and uniformed couriers. High-contrast realism, noisy textures, or flat corporate vector clip-art would break the tactile language completely.
SIGNATURE DETAIL — the thing that makes this design itself
The harmonious union of a dark vertical control rail, warm linen canvas, and isometric matte-clay logistics miniatures framed within clean 20px rounded cards. This combination elevates an otherwise standard utility dashboard into an inviting, premium delivery command center. Misuse typically occurs when developers swap the warm linen backdrop for stark white, flattening the entire spatial hierarchy.
MUST
- Use warm linen (#FAF8F5) for page canvas to avoid the clinical glare of pure white.
- Limit pure white (#FFFFFF) strictly to elevated cards and input fields.
- Confine terracotta (#C84C3E) to call-to-action anchors, active indicators, and narrative highlights.
- Pair numeric metrics with supporting iconography enclosed in soft-tinted square squircles.
AVOID
- Do not apply heavy drop shadows; cards should rely on 1px subtle borders (#EDE8DF).
- Never replace the terracotta accent with bright saturated blues, purples, or generic reds.
- Avoid sharp 0px corners; every container must adhere to the 10px or 20px radius system.
- Do not place photographic assets where stylized clay isometric illustrations belong.
