Display and reading settings

All of these live in an adventure's Settings (the gear icon) under Gameplay → Display.

Text#

Text size — Normal or Large. Large makes the whole interface about a quarter bigger, not just the story.
Text style — Print (a book-like serif, the default), Clean (a modern sans-serif) or Hacker (monospace).

Theme — Dark (the default) or Light.
Styled themes — a full palette swap: background, text, buttons and borders all change together. Choose from:

Theme	Feel
Ironwood	Warm browns with an amber accent
Voidglass	Deep indigo with a violet accent
Emberfall	Near-black with a fiery red-orange accent
Verdant	Dark forest green with a leafy accent
Tidewater	Deep navy with a bright blue accent

To go back to the plain look, choose Dark or Light again.

Under Gameplay → Models → Prototype there are three small formatting options:

'>' markers on actions — adds a > before your Do actions when they're sent to the AI.
Action paragraph spacing and Continue paragraph spacing — adjust how line breaks are handled.

Narration speed and volume are under Gameplay → Narration — see Narration (read aloud).
