Player interface
What the player sees is set on the Player interface tab at the top of the blueprint. The tab shows the card as a player opens it; the panel in the top-right edits it, and Exit in the top-left returns to the blueprint. Along the top: Inspect, Look, Desktop / Phone.
Look: theme and layout
Look opens a panel in two parts.
Layout decides what is on the card: Conversation only, Portrait scene, Adventure HUD, Stat panel, Character sheet. Each one says which variables it adds — "Adventure HUD", for instance, adds location, day, time of day, stamina, energy, inventory and relationships. They are ordinary variables afterwards: visible on the board, editable, drivable by a behaviour.
When you switch layouts, variables the previous layout created, the new one does not use and nothing else references are not deleted behind your back. A pill appears at the bottom — "the previous layout left N variables nothing else uses" — and Clear them removes them, undoably. Close the pill to keep them.
Theme decides colour, type and corners: no theme (the platform's default look), Paper, Night, Terminal, Blossom. A theme changes only how the card looks, never anything you wrote.
Inspect: click it, change it
Press Inspect, then click any part of the picture — the title, a meter, a button, the input box — and the right panel becomes its editor: text and size, weight, colour, position and dimensions; a meter can also add a status. Once a part is selected, clicking another part switches to it without pressing Inspect again; a click on empty space outside the card puts the selection down; Esc, or closing the panel, hands the card back to itself.
Desktop and phone
Desktop and Phone at the top switch the preview width. Each width keeps its own positions and sizes, and you edit the one you are looking at.
After saving
Save, and the playtest and the player both get this layout and theme. The embedded playtest renders the template without going full screen; when a player opens the card, the full-screen player view is exactly what you see here.
