Mobile only (<=639px / coarse pointers); desktop keeps its behaviour. Foundation - lib/motion.ts owns the spring presets (snappy/gentle/sheet), durations, easings and variants (screens, tabs, wizard steps, list stagger). - Native-feel CSS: press feedback scales every button, card, chip, tab, row and summary to 0.96 with a spring-like cubic-bezier on transform (scoped to phones/coarse pointers), tap-highlight off, touch-action manipulation, chrome text non-selectable, reduced motion drops it. - App shell fades in once on launch; the study feed fades in on phones. Applied - Tab bar: sliding active pill (shared layoutId) + icon bounce. - Study Decks/Homework, language toggle, difficulty and size pickers: the same gliding highlight, gated so desktop keeps the old styling. - Route content enters direction-aware (deeper = from the right, back = from the left, same-depth = crossfade) via RouteTransition on the library/create/homework content columns; library tab switches crossfade; wizard steps slide forward/backward (reduced motion safe). - Library: cards fade up in a capped stagger on first load, glide with layout animations and shrink away on delete (AnimatePresence). - Study feed: correct feedback pulses, wrong shakes, the progress bar settles with a spring curve, score and XP count up on the results. - Settings sheet uses the sheet spring; the drawer now follows the finger and closes on release velocity, like the sheet. - Generation progress: the stage message fades/slides between stages; the icon keeps its gentle wobble; the feed fades in on hand-off. Skipped, on purpose: LazyMotion (the sliding highlights need layout animations = domMax, same features the current import already has); route exit animations (the App Router unmounts the outgoing page — exits are handled by in-page AnimatePresence); replacing the study feed's native scroll-snap with finger-follow drag (would fight the platform scroller); finger-follow height animation for native <details> expanders. Verified: animation suite 8/8 (reduced motion + 4x-CPU-throttled trace: no long tasks, CLS 0.0000), regression 74/74, mobile 52/52, declutter 116/116, i18n 25/25. Lint + build clean. SW freezmo-v21.
