/* Right detail pane — content swaps based on the active left button.
   Fixed height (not just min-height) pins the modal shape across tab
   switches so it stays the same size regardless of which option the
   teacher clicks. The "Plan a unit" pane is the densest (class chips
   + CTA) and sets the floor. Shorter panes (Connect Google / Open
   settings) keep the same shell; any pane that overflows scrolls
   internally rather than stretching the modal.
   Flex column + margin-top:auto on the CTA row pins the action button
   to the bottom-right of the pane regardless of how much content sits
   above it. Same trick used in gh-split placeholders for visual parity. */
