 review:
-  strengths:
-  - Correct ECDF implementation using stat_ecdf(geom='step') — idiomatic grammar-of-graphics
-    approach that computes the distribution natively
-  - 'Perfect code quality: KISS structure, reproducible seed, clean imports, correct
-    output filenames for both PNG and HTML'
-  - Realistic and well-chosen data scenario (web service response times with bimodal
-    exponential+normal distribution)
-  - 'Full theme-adaptive chrome: PAGE_BG, INK, INK_SOFT tokens applied correctly across
-    both light and dark renders'
-  - Explicitly set font sizes (24pt title, 20pt axis labels, 16pt ticks) matching
-    the style guide requirements
-  - 'Brand green #009E73 used correctly as the single-series color, consistent across
-    both renders'
-  weaknesses:
-  - 'Grid lines are too prominent: GRID colors (#C9C7C1 light / #565551 dark) are
-    ~2.5x more opaque than the style guide''s recommended rgba(26,26,23,0.10) — grid
-    competes with the data line rather than fading into the background'
-  - 'No data storytelling: the bimodal distribution shape (exponential fast-path +
-    normal slow-path) is a clear insight that goes unexplained — key percentile markers
-    (e.g. p50, p90) or a note about the two populations would lift DE-03'
-  - 'Title format does not match required spec: should be ''ecdf-basic · letsplot
-    · anyplot.ai'' — the descriptive prefix ''Web Service Response Times · '' makes
-    it a 4-part title instead of the prescribed 3-part format'
-  - 'LM-02 is minimal: the implementation uses stat_ecdf which is available in any
-    ggplot-style library; lets-plot''s distinctive interactive capabilities (tooltips,
-    HTML export) are not leveraged in the plot layer itself'
-  image_description: |-
-    Light render (plot-light.png):
-      Background: Warm off-white consistent with #FAF8F1 — not pure white, correct brand surface.
-      Chrome: Title "Web Service Response Times · ecdf-basic · letsplot · anyplot.ai" rendered in dark ink at top-left; axis labels "Response Time (ms)" (x) and "Cumulative Proportion" (y) clearly readable in dark ink; tick labels at 0/0.25/0.5/0.75/1.0 (y) and 0–270 (x) readable in dark-soft ink. All text visible against the light background.
-      Data: Step-function ECDF rendered in #009E73 (brand green); line is clearly visible with size=2 (scaled 6px). The characteristic bimodal shape shows a fast initial rise (exponential component) followed by a plateau then second rise (normal component). Grid lines (both axes) in medium warm gray — somewhat prominent but not overwhelming.
-      Legibility verdict: PASS — all text readable, no light-on-light issues.
-
-    Dark render (plot-dark.png):
-      Background: Deep warm near-black consistent with #1A1A17 — not pure black, correct dark surface.
-      Chrome: Title and axis labels rendered in light off-white (#F0EFE8); tick labels in light secondary ink (#B8B7B0). All text elements clearly visible against the dark background. No dark-on-dark failure observed.
-      Data: ECDF line is identical #009E73 green — data colors unchanged from light render, only chrome has flipped. Grid lines appear in a muted warm gray (#565551), somewhat visible but more subtle than in the light render.
-      Legibility verdict: PASS — all text readable in both themes, no dark-on-dark issues detected.
