Design a light-mode mobile app interface screen: cinematic dark photography headers transitioning into crisp white cards anchored by electric cobalt accents.
LAYOUT
The interface executes a top-to-bottom transition from dark cinematic immersion to functional utility. The hero segment occupies the upper 40% with dark photography, brand badge, headline, and an overlay floating menu anchored top-right. Below, the sheet transitions to an off-white canvas with 20px edge margins, stacking an asymmetric two-column 'About' block, followed by a horizontally swipeable 'Services' tray and peeking 'Selected Work' cards.
PALETTE (use these exact hex values)
- #f8fafc — Canvas Off-White: Main screen background for all content areas beneath the hero fold
- #ffffff — Card Surface: Background for floating service tiles, stat pods, and floating content sheets
- #0e1118 — Hero Obsidian: Deep photographic backdrop and vignette floor for the top viewport area
- #161b26 — Nav Menu Surface: Background of the floating top-right persistent vertical navigation drawer
- #2563eb — Cobalt Blue: Active navigation pill, section indicator rule, pagination indicator, and play glyph
- #f59e0b — Brand Amber: Geometric diamond logo badge glyph beside white brand initial
- #0f172a — Heading Dark: Primary headings, title cards, and high-emphasis labels on light surfaces
- #64748b — Body Slate: Body copy, card descriptions, inactive icons, and supplementary statistics labels
- #94a3b8 — Muted Text Inverted: Hero preheadings and subtext displayed against the dark photographic backdrop
TYPOGRAPHY
Typeface Plus Jakarta Sans (or Inter, SF Pro Text, DM Sans), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 15px body, 17px subheading, 20px heading, 32px display. Tracking -0.02em for headings, 0 for body. The typography relies on Plus Jakarta Sans (or tight neo-grotesques like Inter) to deliver a confident, contemporary product-studio aesthetic. Large bold display weights (-0.02em tracking) set a commanding tone against dark media, while neutral regular weights ensure scannable readability in metadata and dense statistics pods. Free alternatives like Inter or DM Sans match the structural neutrality perfectly without compromise.
GEOMETRY & SPACING
Corner radii — cards 20px, links 4px, inputs 12px, buttons 999px. Spacing on a 4px unit, 16px gaps, 28px between sections, 390px container, comfortable density.
DEPTH
Depth is produced through discrete surface floating rather than heavy shadows. The primary elements (cards, stat bar, floating menu) utilize soft, multi-layered drop shadows (0 8px 24px rgba(15, 23, 42, 0.05)) that lift white containers cleanly off the subtle #f8fafc backdrop. The dark top drawer uses a slightly stronger elevation (0 12px 32px rgba(0, 0, 0, 0.35)) to float crisply over photographic hero elements.
IMAGERY
Photography adopts an editorial, cinematic standard: close-cropped studio portraits in stark monochrome or Moody, low-key lighting. Subjects are focused professionals engaged in creative or technical work. Saturated, casual stock photography or playful 3D cartoon illustrations would fundamentally break the high-end creative agency mood.
SIGNATURE DETAIL — the thing that makes this design itself
The design's unmistakable signature is the pairing of the 3px vertical cobalt (#2563eb) bar preceding each section heading with the persistent, dark floating vertical menu drawer anchored top-right. It establishes an architectural anchor point across alternating dark-to-light backdrops. Misusing it means omitting the vertical bar or flattening the floating menu into a standard full-width top navigation bar.
MUST
- Anchor all major section headers with a 3px rounded vertical cobalt (#2563eb) bar.
- Use generous 20px corner radii on all card surfaces to maintain soft tactile hierarchy.
- Retain the floating dark vertical navigation drawer in the top right quadrant over media.
- Tint squircle icon containers with subtle, distinct pastel tones to visually segment feature sets.
AVOID
- Do not remove the vertical cobalt bar from section titles; it is the core branding motif.
- Avoid sharp 0px or small 4px border radii on cards or floating menu sheets.
- Do not use full-width solid black backgrounds below the hero scroll threshold.
- Never replace the white circular play button with a translucent or borderless icon.
