Scaffold a token-based shadcn/ui + Radix primitive set (select/combobox/command/switch/tooltip/form/drawer/…) matching a codebase's house conventions on Tailwind v4 — semantic-token colors, a global focus ring, no tailwindcss-animate, 44px touch targets, forwardRef like the existing button. Use when an app hand-rolls or fakes controls (native `<select>`s, `title=` tooltips, custom dropdowns, DIY meters), or when standing up shadcn/ui on Tailwind v4.
