 review:
   strengths:
-  - 'Perfect spec compliance: correct lollipop type with stems and dots, sorted data,
-    all required features present'
-  - 'Strong theme adaptation: both renders pass legibility with correct background
-    and text color tokens throughout'
-  - 'Intentional focal emphasis: Electronics dot sized at 2x others using alt.condition
-    — evidence of design thinking beyond defaults'
-  - Interactive hover with selection_point and opacity dim/highlight showcases Altair
-    distinctive declarative interactivity
-  - 'Clean KISS code: deterministic data, all imports used, elegant layer composition
-    with + operator'
-  - 'Correct canvas handling: pad-to-3200x1800 logic with fail-loud on overshoot'
+  - Correct lollipop chart with proper mark_rule stems and mark_circle dots — all
+    spec requirements satisfied
+  - 'Focal emphasis: Electronics dot rendered at size=950 vs size=480 for others,
+    creating clear visual hierarchy'
+  - Annotated top performer with bold '$425,000' value label guiding viewer to key
+    insight
+  - Interactive hover selection (alt.selection_point) with opacity dimming — Altair-native
+    feature active in HTML output
+  - 'Perfect theme-adaptive chrome: all text, grid, and legend tokens correctly flip
+    between #FAF8F1 and #1A1A17 surfaces'
+  - Idiomatic Altair layer composition (stems + dots + annotation) using alt.datum
+    expressions and alt.condition
+  - Sales data sorted descending — reinforces ranking narrative immediately
+  - 'Both renders fully legible: no dark-on-dark or light-on-light text failures'
   weaknesses:
-  - 'DE-03: No value annotation or reference line to anchor the viewer story — add
-    a text label on the Electronics dot showing $425K or a horizontal mean reference
-    line'
-  - 'DE-02: Axis domain lines still visible (domainColor=INK_SOFT) — add domainOpacity=0
-    to configure_axis for a cleaner minimal aesthetic'
-  - 'VQ-01 minor: 10 rotated x-axis labels at -35 deg are readable but slightly dense
-    — labelAngle=-45 with labelFontSize=9 would improve spacing'
+  - 'DE-01 (5/8): Design is intentional and above defaults but not yet at publication-quality
+    polish — typography hierarchy could be tighter and marker stroke effect could
+    be more refined'
+  - 'DE-02 (4/6): Tick marks still visible on both axes; removing or reducing them
+    would sharpen the minimalist look; domain opacity=0 hides axis line cleanly but
+    tick color remains'
+  - 'DE-03 (4/6): Storytelling is good but could be elevated — consider color-fading
+    all bars below top-3 slightly to deepen the ranking story beyond size variation'
+  - 'VQ-01 (7/8): Annotation font at fontSize=10 is the smallest element; at mobile
+    width (~400 px) it scales to ~5 px — slightly below comfortable threshold; consider
+    fontSize=11-12 for the annotation'
+  - 'LM-02 (4/5): Interactive selection and alt.datum expressions are Altair-distinctive,
+    but the HTML-rendered interactivity is invisible in the static PNG — consider
+    adding a text annotation or legend note referencing interactivity, or showcase
+    another Altair-unique static visual encoding'

     Light render (plot-light.png):
-      Background: Warm off-white #FAF8F1 — correct theme background.
-      Chrome: Title "Product Sales by Category · lollipop-basic · python · altair · anyplot.ai" in bold dark ink, ~70% width — readable. Y-axis label "Sales (USD)" and X-axis label "Category" in dark INK tone — readable. Y-axis tick labels ($0–$450,000) and X-axis category labels (rotated -35°) in muted INK_SOFT tone — all readable.
-      Data: Brand green #009E73 stems (strokeWidth=4 vertical rules) and circular dots. Electronics dot is noticeably larger (size=950) as a focal emphasis. All 10 categories visible with lollipop from $0 baseline to value. No overlapping elements.
-      Legibility verdict: PASS
+      Background: Warm off-white (#FAF8F1) — correct, not pure white
+      Chrome: Bold title "Product Sales by Category · lollipop-basic · python · altair · anyplot.ai" in dark ink, clearly readable; "Category" X-axis label and "Sales (USD)" Y-axis label both readable dark text; Y-axis tick labels ($0–$450,000 in dollar format) and X-axis category tick labels (rotated -45°) all legible against the light surface; subtle horizontal grid lines in INK at 12% opacity
+      Data: 10 lollipop stems in brand green #009E73 (mark_rule, strokeWidth=4); circular markers in same #009E73 with PAGE_BG stroke ring for separation; Electronics marker is distinctly larger (size=950) creating focal emphasis; "$425,000" annotation in dark ink above Electronics dot
+      Legibility verdict: PASS — all text clearly readable, no light-on-light failures
 
     Dark render (plot-dark.png):
-      Background: Warm near-black #1A1A17 — correct theme background.
-      Chrome: Title in bold light text (#F0EFE8 tone) — readable. Axis labels and tick labels in light muted tone (#B8B7B0 tone) — readable. No dark-on-dark failures. Tick label text is clearly distinguishable from the dark background.
-      Data: Data colors (brand green #009E73) are IDENTICAL to the light render — only chrome has flipped. Stems and dots carry identical color. Electronics larger dot is preserved. Grid lines appear as subtle light lines on dark background.
-      Legibility verdict: PASS
+      Background: Warm near-black (#1A1A17) — correct, not pure black
+      Chrome: Title and axis labels in light off-white (INK=#F0EFE8) — fully readable against dark surface; Y-axis and X-axis tick labels in INK_SOFT (#B8B7B0) — clearly visible; grid lines subtle against dark surface; "$425,000" annotation in light text, legible
+      Data: Stems and dots in identical #009E73 brand green — matches light render exactly; Electronics dot still distinctly larger; no hue shift between themes (data colors theme-invariant, only chrome flips)
+      Legibility verdict: PASS — no dark-on-dark failures; all chrome tokens correctly adapted to dark theme; brand green #009E73 remains visible and distinguishable on dark surface
