Now I have a clear picture of the structure. The left panel has collapsibles: Full Package Settings, Sessions, Session Blocks, Advanced Options. The user wants a new tab elsewhere (not in the existing left panel) that shows a static visual/preview of what those dropdowns look like when mandatory fields aren't filled. Let me read the top-level layout to find where to add a new tab:

Now I understand the full structure. There's no existing tab system — the UI is a single large panel. The best approach is to add a small tab bar at the top of the left "Program Settings" panel with a second tab called "Requirements" that shows the locked-state visuals. This keeps it completely separate from the current UI while being contextually sensible.

Now I have everything I need. I'll add a settingsTab state, replace the static "Program Settings" header with a two-tab header ("Settings" | "Requirements"), and render the locked-state visual under the "Requirements" tab.

Now replace the panel header with the two-tab header and add the Requirements tab content:

Now I need to close the settingsTab === 'requirements' ? ... : ( ternary — add the closing )} and a </div> right before the panel's closing </div>. Let me find the exact end of the settings panel content:

Now let me find the exact closing of the settings panel </div> after all collapsibles:

I can see the structure clearly. Lines 1576–1577 are the two closing </div> tags for the settings content div and the panel wrapper div. I need to close the ternary ()}) before those closing tags:

A "Requirements" tab has been added to the Program Settings left panel alongside the existing "Settings" tab. Clicking it shows a static visual mockup of the locked state for both sections: the Sessions panel displays an amber info banner reading "Sessions cannot be created without first configuring the required Program Package details: Title, Start Time, and Price," and the Session Blocks panel shows "At least one session must be created before session blocks can be configured." Both locked panels include a greyed-out, disabled "Add" button to visually reinforce the unavailable state.

I have both locations. Line 1219 has Added Sessions and line 1394 has Created Blocks. I'll read each exact snippet then edit them.

Now I also need to check what state setter clears sessions and blocks:

I have everything. Now both edits:

Added a "Clear All" button inline with the "Added Sessions" label that calls setSessions([]), and the same next to "Created Blocks" calling setSessionBlocks([]). Both buttons use the destructive color token and a subtle hover state to signal the action's consequence without being visually disruptive.
