Expand any atlas into full event cards

Every atlas row on the timeline now has an expand button (▼) next to its name. An expanded row shows its events as cards with titles and descriptions, laid out along the timeline.

• Starred events stand out: they get larger featured cards with a thumbnail and more of the description.
• You set the height: choose how many rows of cards sit above and below the line, either from the gear next to the expand button or in the Atlas inspector under Expanded view card rows. Set both to 0 for a compact row of dots.
• Busy moments stay readable: when there's no room left, events merge into a group card. Hover it to see the full list in date order.
• Tagged events show as small chips with a tag icon, so you can tell them apart from the atlas's own events.

Card row settings are saved per atlas with your project.
