Design a light-mode mobile app interface screen: misty alpine dawn awakening quietly into deep pine biometrics and luminous teals.
LAYOUT
Vertical single-column mobile flow starting with an integrated landscape art header and centered morning greeting. The primary night hero card occupies the upper third, transitioning seamlessly into stacked daytime telemetry cards. A standardized 16px lateral margin bounds all cards, concluding with a persistent floating bottom tab bar.
PALETTE (use these exact hex values)
- #F7FAF8 — Canvas Ground: overall app background behind all cards and scrollable content
- #0D3A3B — Deep Boreal Teal: primary nocturnal container background for hypnogram and sleep duration
- #FFFFFF — Pure Card White: daytime metric cards, icon buttons, and navigation bar
- #2CC49A — Luminous Mint: deep sleep bars, progress indicators, donut gauge stroke, and primary FAB
- #78D8CD — Soft Aqua: REM sleep hypnogram stages and secondary biometric markers
- #A8E5DE — Pale Foam: light sleep stages in charts and subtle progress backgrounds
- #F7BE98 — Sunrise Apricot: awake status intervals, sunrise glow accents, and achievement stars
- #132524 — Midnight Pine Text: high-contrast titles, primary metrics, and active tab icons
- #768B87 — Misty Forest Text: secondary metric labels, subtitles, timestamps, and inactive icons
- #EBF1EE — Subtle Ridge Border: light borders surrounding daytime metric cards and vertical column dividers
TYPOGRAPHY
Typeface Plus Jakarta Sans (or SF Pro Display, Outfit, Inter), weights 400/500/600/700. Sizes 11px caption, 13px body-sm, 15px body, 17px subheading, 22px heading, 28px display. Tracking -0.02em at large numbers, 0 at captions. The typographic tone is tranquil, clinical yet deeply human, utilizing rounded geometric letterforms. Large numbers command instant readability while generous letter spacing on captions keeps dense clinical data intelligible. Plus Jakarta Sans or SF Pro Rounded provides the exact balance of digital precision and bedtime serenity.
GEOMETRY & SPACING
Corner radii — cards 24px, links 999px, inputs 16px, buttons 999px. Spacing on a 4px unit, 12px gaps, 20px between sections, 390px container, comfortable density.
DEPTH
Depth is predominantly planar, relying on high-contrast surface color switches between dark teal and clean white. Floating circular buttons and cards cast microscopic, diffuse ambient shadows (0 4px 20px rgba(13, 58, 59, 0.05)) without directional offsets. The center navigation FAB uses slight elevation to hover neatly above the docked bar.
IMAGERY
Vector-based environmental landscape featuring layered misty pine ridges, a cozy cabin silhouette, and a gentle morning sun. The illustration style uses muted greens, pastel apricots, and smooth atmospheric gradients. Photorealistic stock or harsh 3D glossy renders are strictly off-brand.
MUST
- Anchor nocturnal telemetry inside deep teal containers and daytime scores in crisp white cards.
- Use 24px corner radii for all primary card containers to preserve softness.
- Render the hypnogram chart with sharp stepped intervals matching the 4 defined sleep stages.
- Keep icon strokes clean, light, and monochrome teal-slate (#768B87).
AVOID
- Do not introduce pure black (#000000); use midnight pine (#132524) for deep contrast.
- Do not use sharp 0px or 4px square corners anywhere on cards or buttons.
- Do not use high-saturation reds or harsh yellows; use soft sunrise apricot (#F7BE98) instead.
- Do not clutter metric tiles with heavy drop shadows; rely on borders (#EBF1EE) and surface contrast.
