+/**
+ * QA test plan "cloud 1.50 → 1.51", Asset Management (#14347, #14765, #14848,
+ * #14858): shift-click and Ctrl/Cmd-click must multi-select video assets the
+ * same way they already do for image assets.
+ *
+ * Video is the one media kind that needs its own coverage here. A plain click
+ * on a video card is deliberately swallowed — `MediaAssetCard.handlePreviewClick`
+ * returns early for `fileKind === 'video'` so the click plays the clip instead
+ * of selecting it — and that early return is skipped only while a selection
+ * modifier is held. The modifier paths are therefore the *only* way to build a
+ * multi-selection on video, and a regression in that guard would silently make
+ * video assets unselectable while images kept working.
