The "Gotcha" here is that very dark or large shadows can make the UI look heavy or cluttered. Compare the two cards below.
This card uses `shadow-md`, a commonly recommended shadow size. It provides depth without being overpowering.
This card uses `shadow-2xl`. Notice how much heavier it feels compared to `shadow-md`. Overusing such large shadows can lead to a cluttered interface.
Consideration:
While larger shadows (`shadow-lg`, `shadow-xl`, `shadow-2xl`) have their place for emphasis (e.g., modals, focused elements), using them ubiquitously for all cards can make the UI feel heavy. Stick to subtler shadows like `shadow-sm` or `shadow-md` for general card elements unless a stronger shadow serves a specific design purpose.
