📋 What was this drill?

Drill: Dark mode native: build a dashboard on #08090a (Linear-style). Depth via luminance stepping, not shadows. Borders at 5-8% white. Target: looks designed-for-dark, not inverted.

Interpretation: Building an aquarium life-support (LSS) night-rounds console — a domain where dark UI is ergonomically native (05:12 pre-opening rounds). New structural variables for the series: an SVG flow-schematic hero, stroke-only sparklines on dark with a dashed band-max threshold, and a 24h lighting-phase strip with a live NOW cursor. Accent = magenta #e08ac2 (grow-light spectrum) contracted to exactly 4 roles, with the selected-row role pre-seeded so every role renders in the static capture; Linear-style luminance ladder with 5%/8% white borders only, zero shadows.
