 Marimo only shows **what you `return` from a cell**. Calling `mo.vstack(...)` or `hm.query_result(...)` without returning it produces no visible output.
 
-See `examples/hotdata_basic.py` for a full notebook: five Python cells (`mo.vstack` for **controls only**, then a separate cell `return hm.query_result(editor.result)` so results show immediately — **avoid** `mo.lazy` here: it only renders after the block scrolls into view, which looks like an empty cell). If Marimo shows **empty cells**, quit and remove `examples/__marimo__/` so the UI reloads from the `.py` file only.
