Animations are language-independent

Text layers can be replaced dynamically via AE or runtime

JSON assets can support localized text

Works across all locales without extra setup

Dynamic updates possible for multi-language apps

Animations should respect prefers-reduced-motion

Use semantic UI elements with Lottie overlays

Do not convey critical information solely via animation

Alternative static visuals for screen readers

Avoid rapid flashing content for sensitive users

Animations integrate into UI container

Independent of app styling except size/position

Responsive-friendly if container scales

Overlays handled via platform UI

Vector graphics remain sharp on all devices

Playback state: play, pause, stop

Looping and speed adjustments

Dynamic property overrides

User interaction triggers events

No global app state dependency

JSON files contain all animation data

Minimal runtime memory footprint

Dynamic properties managed via JS or SDK

Multiple animations can share JSON templates

Cache animations to reduce repeated parsing
