T8b949e/**

* Returns a [CornerBasedShape] for a message bubble based on its position in a sequence.

*

* Standalone bubbles are fully rounded; consecutive bubbles from the same sender flatten only the corners facing each

* other (to [groupedCornerRadius]) so a run reads as one visual group, matching the M3 conversation pattern.

*

* @param cornerRadius The base corner radius for the bubble.

* @param isSender Whether the message was sent by the local user.

* @param hasSamePrev Whether the previous message in the list is from the same sender.

* @param hasSameNext Whether the next message in the list is from the same sender.

* @param groupedCornerRadius The reduced radius used on corners adjacent to a same-sender neighbor.
