Does a cascade count as part of the action that added the original Blight (e.g., for effects that care about Blight being added during a Ravage Action)?

• The "Destructive Nature" special rule of Heart of the Wildfire protects its Presence from cascades caused by Spirit Actions.
• Against the Habsburg Monarchy (Livestock Colony), if a single Ravage Action causes 8+ Damage to a land, then all of the Blight cascading from that Ravage also counts towards the Adversary's "Irreparable Damage" loss condition. (In solo play, this causes an immediate loss.)
• Against the Tsardom of Russia Level 1+, Blight cascading from a Ravage destroys Beasts tokens due to "Hunters Bring Home Shell and Hide," possibly harvesting multiple Beasts tokens from a single Ravage Action.
• Against the Kingdom of Scotland Level 5+, Blight cascading into a Coastal land from a Ravage triggers the extra Blight from "Runoff and Bilgewater" even if the Ravage Action was in an Inland land or on a different board. If Blight is added into multiple Coastal lands this way due to a single Ravage Action (e.g., if a Ravage in a Coastal land cascades into another Coastal land), only trigger "Runoff and Bilgewater" once. (Thus if a single Ravage Action adds Blight into Coastal lands on multiple boards, player choose which of those boards is "that board" for "Runoff and Bilgewater.")
