📋 What was this drill?

Drill: Status semantics: a notification list using only semantic colors (success/warn/danger/info). Each status must be distinguishable to colorblind users (shape + color, not color alone).

Interpretation: Building 'Falstone Grid — Westlink', a 132/33 kV transmission-substation alarm desk where severity (crit/major/minor/advisory: glyph silhouette + rail + tint + word chip) and lifecycle (unack ringed tile / ACK stamp / RTN corner-check / resolved muting) ride two fully orthogonal encoded scales. Cool near-white console, Inter + JetBrains Mono, WCAG-clamped semantics, in-legend grayscale proof strip, live acknowledge interactions.

    Grayscale proof — rendered through a color-vision filter, every severity and lifecycle state above stays readable by shape, ring, stamp and muting alone.
