Brand & Experience Presets

Each theme keeps its own look memory under tenant_landing_config.config.theme_presets[themeId] (lib/branding/theme-presets.ts).

What is stored in a preset

Look keys: colors, logos, fonts, navbar, section toggles, and similar chrome — not SEO / product / content keys.

Action	Effect
Apply theme B	Snapshot current theme A → `theme_presets[A]`; restore `theme_presets[B]` or package seed
Brand & Experience save	Refresh `theme_presets[active_theme_id]`
SEO / product / content	Global — Apply never overwrites

Empty presets behave like legacy seed-only Apply for new tenants.
