/* shadcn/ui components, ported to plain CSS (no React, no Tailwind, no build step).
   Source of the values: the shadcn registry, style "new-york-v4" (https://ui.shadcn.com/r/styles/new-york-v4/<name>.json,
   read 2026-11-11): button, input, label, card, badge, separator, textarea, dialog, tabs, accordion, switch, slider,
   toggle-group, dropdown-menu, progress, alert (the last three read 2026-11-12). Each Tailwind class was turned into the CSS it stands for (h-9 = 36px, rounded-md = --radius-md,
   shadow-xs, ring-[3px] ring-ring/50 = --focus-ring, and so on).
   Our markup keeps its own class names (.btn, .seg, .switch ...) and its ARIA roles, so the editor's scripts and tests
   do not change. A native <select> and <input type="range"> are styled to look like shadcn's Select and Slider.
   Where we differ from shadcn on purpose, the rule says so. */
