补 dataviz 缺口的正規版：a categorical palette run through the dataviz skill's colorblind validator (worst adjacent CVD ΔE 24.2, PASS), plus sequential and diverging scales, and component specs for axes, legends, tooltips. The preview renders real bar/line/donut demos in the system's own colors.
補足圖表缺口的正規版：分類色票跑過 dataviz skill 的色盲驗證器（最差相鄰 CVD ΔE 24.2，通過），另含漸序與發散色階，以及軸線/圖例/tooltip 元件規格。preview 用系統自己的配色實際畫出長條/折線/圓餅示範。
Design Notes
Inter + IBM Plex Mono for numerals; the neutral analytical default when charts must be legible and colorblind-safe.
Inter 配 IBM Plex Mono 數字；當圖表必須清晰且色盲友善時的中性分析預設。
