2025-12-18 01:25:00 - Mobile Touch Prevention on Pack List

User Request

The user requested to disable the hover-to-preview functionality on touch screens in the draft management pack list and instead use long-press to open the preview, matching the behavior on small mobile screens.

Implementation Details

Modified CardPreview.tsx to update the CardHoverWrapper component.

  • Changed isMobile detection logic from a simple window.innerWidth < 1024 check to a more robust check that includes window.matchMedia('(pointer: coarse)').
  • Removed (hover: none) from the check to ensure devices that report hover capability (like some tablets with styluses) but are primarily touch-based are still treated as mobile.
  • This ensures that devices with touch capabilities (like tablets) are treated as "mobile" by the component, disabling the default hover behavior and enabling the long-press gesture for card previews.
  • This change affects CubeManager (Pack List) and any other component using CardHoverWrapper (e.g., StackView inside PackCard).

Risk Handling

  • Verified that DraftView uses its own touch logic (useCardTouch) so it remains unaffected (though it behaves similarly).
  • Ensures that touch laptops (which might support hover) are not aggressively forced into mobile mode unless they match hover: none (which usually targets tablets/phones). This tries to preserve mouse functionality where available, although the user's request was specific to "touch screens". The hover: none media query is the standard way to detect touch-primary devices.
