Refined Preview Suppression

Objective

Tune the "Smart Preview Suppression" logic to better align with the Stack View's behavior. In Stack View, hovering a card causes it to "pop" to the front (z-index shift), making the card fully visible in-place. Because of this, showing a floating preview is redundant and distracting once the card is large enough to be read directly.

Changes

  • Modified handleMouseEnter in src/client/src/components/CardPreview.tsx:
    • Lowered the suppression threshold from >240x300 to >200x270.
    • Logic:
      • Cards sized via the slider to be larger than 200px wide are now considered "readable" (especially since the 'Art Crop' mode turns off at 170px, leaving a range of 170-199 where preview is explicitly ON for text, and 200+ where it's suppressed).
      • This effectively disables the popup in Stack View for medium-to-large settings, relying on the native "pop-to-front" hover effect for inspection.

Result

A cleaner, less jittery drafting experience where large cards simply "lift up" for inspection, while smaller cards still get the helpful magnified popup.
