The pick target grows from the read-only textarea to the full capsule:
the card owns the click, its disabled controls let pointer events fall
through, and a dashed l4 stroke with a business-blue hover marks the
affordance (an SVG dash ring — native dashed has a fixed pattern). The
card contains pointerdown so the open picker's outside-close cannot
race the reopen, which flickered the chip's expansion echo.
