📋 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: Built an observatory night-operations desk (fictional 2 m telescope, 03:21 LT live sheet): 6-KPI conditions strip, 11-column exposure queue, hourly sky table, systems panel, procedural exceptions register. Luminance ladder #08090a→#0e0f12→#14161a with 6% white hairlines and zero box-shadows enforced by lint; one instrument-cyan accent reserved for LIVE/NOW semantics; 17 on-load audit checks reconcile every figure.

Aggregation notes Seeing figures are hourly medians of 60 s DIMM samples; tonight's page median is 1.04″ against the 18:00 forecast of 1.15″ — the forecast ran 0.11″ conservative. Duty cycle 32.0% of usable dark time; overheads (slews, dithers, readout, filter changes) take 68.0%. Data volume 93.6 GB = 78 frames × 1.20 GB + 21.6 GB calibrations.
