Identity: look and voice

On the Identity tab:

• Logo — used as the watermark on renders (when the watermark widget has no own image) and shown across the app.
• Colors — a primary and an accent. The accent is the default color for animated hook/endcard titles, so motion titles pick up the brand look without per-stack work (a stack can still override it).
• Niche & audience — free text describing what this brand is about and who it talks to. Every AI text generator reads this, so ten brands don't write in one voice. A toggle excludes the brand from AI context if you prefer neutral output.
• Caption look — pin a caption style for this brand and/or override its colors. The pin is the default for stacks that don't choose a style themselves; a style picked in the stack editor always wins. Color overrides recolor whatever style runs. See Captions.
