Motion preference

WBDS core는 ambient OS state에 semantic behavior를 자동 연결하지 않습니다.

default motion contract: data-wb-motion="full" or omitted;
explicit reduced contract: data-wb-motion="reduced";
products may expose their own preference control;
a product may intentionally translate the OS preference into the explicit WBDS attribute;
no component should silently switch semantic state representation merely because the browser media query changed;
reduced/static equivalents remain required where motion is nonessential, vestibularly risky, or necessary for task completion.

모든 component와 core flow에 공통으로 적용되는 최소 기준입니다.

semantic HTML/native controls first
accessible name/label for every control
complete keyboard path
immediate visible :focus-visible
state is not color-only
minimum target sizing appropriate to pointer mode
explicit motion-reduction path for motion-bearing components
zoom/reflow without horizontal page scrolling for core flows
long Korean/English/Japanese strings and unbroken tokens tested
loading/empty/error/partial/unavailable/disabled states remain understandable
focus is preserved or intentionally moved after dialog, save, error, async completion
async announcements are meaningful and restrained rather than token-by-token noise
component-local horizontal scroll regions remain keyboard reachable; code/table/diff surfaces may scroll locally, but the user must be able to focus and operate the region without a pointer
Light and Dark semantic mappings preserve the same state meaning, focus visibility and accessibility floor
