Cards & Panels

Glass viewing panels into distinct content environments. Each card is a self-contained exhibit, hovering in the dark like a tank illuminated from within.

Standard Cards

🌊

Coral Reef

Home to 25% of all marine species, reef ecosystems are the rainforests of the sea. Delicate structures built over millennia, teeming with color and interdependence.

Saltwater

Jellyfish Gallery

Bioluminescent displays drift through a darkened chamber, pulsing with an ethereal glow. Moon jellies and sea nettles trace silent arcs through the blue.

Kelp Forest

Towering columns of giant kelp sway in the simulated current, sheltering sea otters and garibaldi in a vertical ecosystem of filtered sunlight.

Species Spotlight

The clownfish navigates its anemone host with practiced ease -- a symbiotic bond where venom meets immunity, and both partners thrive in the reef's complex web of survival.

Alerts

System notifications from the tank monitoring network. Each alert level carries a distinct visual signal -- from calm informational readings to emergency protocols.

💧
Water Quality Report

pH levels holding at 8.1 and salinity readings are nominal across all tanks. Next automated test cycle scheduled for 06:00.

System Nominal

All filtration systems are operating within expected parameters. Protein skimmers, UV sterilizers, and circulation pumps report green status.

Temperature Advisory

Tank 7 (Tropical Reef) is trending 2°C above baseline. Chiller unit has been engaged. Monitor closely over the next 30 minutes.

Emergency Protocol

Ammonia spike detected in quarantine tank QT-3. Immediate water change required. Isolate affected specimens and initiate emergency filtration bypass.

Design Principles

The guiding currents of the Aquarium design system. Six principles that shape every decision, from color choices to component spacing.

Through the Glass

Interfaces serve as viewing panels into content. Every container is a window revealing the world within -- never a wall blocking the view.

Depth Layers

Like ocean zones from sunlit surface to midnight depths, visual hierarchy emerges from deliberate layering of light and dark.

Living Color

Against deep backgrounds, accent colors glow like bioluminescent creatures -- vibrant, purposeful, and never overwhelming.

Gentle Current

Every transition flows with the smoothness of underwater movement. No jarring cuts, only graceful state changes.

Contained Wonder

Each section is a curated exhibit. Generous spacing lets content breathe like water between coral formations.

Luminous Focus

Glow draws the eye like light in dark water. Use it sparingly to guide attention to what matters most.
