InstantSearchSelectors.isMobileDevice() method

Check if current device is mobile or tablet (≤ 991 px).

Matches the legacy isMobile(isTabletPortraitMax) threshold used by the old ISW code, which treats tablets up to 991 px as "mobile" for layout decisions (full-width style, container selector, etc.).

Signature:

protected isMobileDevice(): boolean;

Returns:

boolean

True if device width is below the tablet-portrait-max breakpoint
