+review:
+  strengths:
+  - Min/max envelope with band!() is the correct Makie idiom for dense waveform visualization;
+    avoids aliasing while preserving visual density.
+  - Layered opacity system (noise floor 8% → outline 55% → fill 72%) creates professional
+    visual depth without clutter.
+  - Seismogram context delivers a complete, coherent data story with clearly annotated
+    P-wave and S-wave arrivals.
+  - 'Perfect spec compliance: all required waveform features present (filled band,
+    semi-transparent fill, zero-line, envelope rendering, synthetic data).'
+  - Full theme-adaptive chrome wiring — dark render reads cleanly with zero dark-on-dark
+    failures.
+  weaknesses:
+  - P-wave and S-wave annotation labels (fontsize=11) are small at mobile scale (~400
+    px rendering); consider bumping to fontsize=12-13 for marginal readability gain.
+  - Noise-floor band at 8% opacity on dark background is nearly invisible — a minor
+    missed opportunity for consistent visual depth across themes.
+  image_description: |-
+    Light render (plot-light.png):
+      Background: Warm off-white (#FAF8F1) — correct light surface
+      Chrome: Title "Earthquake Seismogram · waveform-audio · julia · makie · anyplot.ai" in dark ink (#1A1A17), clearly visible. Axis labels "Time (seconds)" and "Normalized Amplitude" in dark ink. Tick labels in secondary dark (#4A4A44). All readable.
+      Data: Brand green (#009E73) filled envelope at 0.72 opacity with faint outline strokes at 0.55 opacity. Noise floor band at 0.08 opacity. Dashed vertical arrival markers at 35% ink opacity. P-wave and S-wave text annotations in INK_SOFT.
+      Legibility verdict: PASS
+
+    Dark render (plot-dark.png):
+      Background: Warm near-black (#1A1A17) — correct dark surface
+      Chrome: Title and axis labels in light near-white (#F0EFE8), clearly visible against dark background. Tick labels in secondary light (#B8B7B0). No dark-on-dark failure observed anywhere.
+      Data: Waveform fill color identical to light render — same brand green (#009E73) at same opacity levels. Data colors are theme-invariant as required.
