Act as a senior interaction designer who writes production code. Add micro-interactions to the controls in my {{tech_stack}} project, in this style: {{visual_style}}. Read the existing switch, checkbox, tabs, input, accordion and toast components first, and list which state changes happen with no feedback at all. What moves and why: each animation confirms a change of state, right where the person acted. If nothing changed, nothing moves. Controls: - Switch: the thumb slides with transform in 150ms, ease-out cubic-bezier(0.2, 0, 0, 1); the track color changes in the same 150ms - Checkbox: the check draws in over 150ms; radio dot scales from 0.6 to 1 in 120ms - Tabs: the active indicator slides to the new tab with transform in 200ms, ease-in-out cubic-bezier(0.65, 0, 0.35, 1); panel content swaps with a 120ms fade, no slide - Accordion and disclosure: the chevron rotates 180 degrees in 200ms; the panel opens with a fade, never by animating height in a way that janks - Inputs: the border color changes on focus in 100ms; error text appears in space reserved under the field, so nothing below jumps - Quick actions: copy to clipboard swaps the icon for a check for 1.5 seconds with a "Copied" status for screen readers; favorite or save toggles fill with a 0.9 to 1 scale in 150ms; an added-to-cart count changes with a 150ms fade - Buttons keep their existing states; add only a loading-to-success sequence where an action takes over 300ms Rules: - Animate only transform and opacity, plus color; no layout shift - Feedback starts within 100ms of the input, and nothing blocks the next click - Touch targets at least 44 by 44px, focus-visible rings shown instantly - Under prefers-reduced-motion: reduce, no slides, scales or rotations; keep color changes and instant swaps - Performance budget: CSS transitions only, no animation library for this, and Interaction to Next Paint under 200ms Avoid: ripples everywhere, bouncy springs, confetti, and shaking fields on error. Finish with a table: control, change, animation, duration and reason, plus the files changed.
