Acrylic Effect

Controls the acrylic (frosted glass) strength used by major surfaces (e.g. cards, navigation).

Where to configure

Set in hugo.toml at your site root:

[params.theme]
  # Note: Default acrylic strength (percentage).
  # Range: number between 0 and 95.
  # Higher = more opaque; lower = more transparent.
  defaultGlassStrength = 45

Priority rules

1. User adjustment: readers can change the strength in the settings panel; the saved value takes highest priority.
2. Site config: for new visitors, defaultGlassStrength is used as the initial value.
