Settings: condenser first in radio + help; flatten Model wrapper so its label aligns with the rest

Memory Strategy: replace buggy Dropdown with Radio (4 stacked options); slider value text centered

Slider: flatten the number-input pill (no border) and hide the redundant reset button

Use container=False on Settings widgets — official way to drop the outer block frame on Dropdown/Slider

Memory strategies: rename to upstream (condenser/discard_all/hide_tool_result), describe per inference code; quest-name letter-spacing matches paper microsite

Settings: equalize Textbox/Dropdown height, flatten Slider wrapper, default Temperature to 1.0
