+review:
+  strengths:
+  - 'Perfect spec compliance: filled silhouette, landmark annotations with connector
+    lines, VE note, and start/end labels all present'
+  - Both light and dark renders are fully theme-correct and readable; no dark-on-dark
+    failures detected
+  - Summit Peak receives intentional visual hierarchy via larger marker (size 13 vs
+    9) and taller connector, creating a clear focal point
+  - Idiomatic use of band!() for terrain silhouette — the correct Makie primitive
+    for this plot type
+  - Realistic alpine traverse scenario with plausible French/English mountain naming;
+    neutral geography context
+  weaknesses:
+  - Helper functions lerp_elev and gauss_smooth break the flat KISS Imports→Data→Plot→Save
+    structure — consider inlining or using simpler parameterized noise without named
+    functions
+  - Trail End label at x=80 with right-alignment is tight against the right axis boundary
+    — extend x-axis limit from 82.0 to 84.0 to give the label more breathing room
+  image_description: |-
+    Light render (plot-light.png):
+      Background: Warm off-white #FAF8F1 — correct, not pure white
+      Chrome: Title "area-elevation-profile · julia · makie · anyplot.ai" in dark ink, well-centered. Axis labels "Distance (km)" and "Elevation (m)" in dark INK, proportional at 14pt. Tick labels in INK_SOFT (dark-ish) at 12pt — all readable. Horizontal-only y-grid lines subtle. L-shaped spines (top/right removed).
+      Data: Semi-transparent brand-green (#009E73, ~28% alpha) filled area below the solid #009E73 profile line. Six landmark annotations (Trailhead 983m, First Pass 2753m, Summit Peak 3221m, Col de Neige 2597m, Grand Col 2888m, Trail End 1039m) with thin connector lines and INK_SOFT text. VE ≈ 15× note bottom-right in INK_MUTED. First (and only) series is #009E73.
+      Legibility verdict: PASS
+
+    Dark render (plot-dark.png):
+      Background: Warm near-black #1A1A17 — correct, not pure black
+      Chrome: Title and axis labels in light #F0EFE8 (INK on dark). Tick labels in #B8B7B0 (INK_SOFT on dark). Connector lines in muted light tone. All text clearly readable against dark background. No dark-on-dark failures. Grid lines appear as subtle lighter-toned horizontal rules.
+      Data: Same #009E73 profile line; fill uses higher alpha (~42%) for a richer deep-green silhouette. Data colors identical to light render — only chrome has flipped. Brand green #009E73 clearly visible against the dark background.
