NutUI React proportional scaling on branch feat_resize: runtime --nut-scale-f / --nut-scale-font / --nut-scale-icon from scale-f.ts (H5) and scale-f.taro.ts (Taro), Sass helpers scale-px / scale-font-px / scale-icon-px and theme font tokens in variables.scss & theme-*.scss; npm run build / build:taro run scripts/px-to-scale-px-in-component-scss.cjs on component SCSS in memory; profiles standard / large / elderly; commit-backed rules e.g. never scale 0px. Use when implementing 多尺寸适配, 等比适配, 大字版, 老年版, scale-px, viewport or native bridge scaling, or editing component SCSS for resize; SCSS: prefer calc($token + Npx) over #{} in calc, use outer calc() when mixing tokens that compile to var(--nutui-*).
