[Coding/Content] Ex

Ex is coded when the main content is an explosion or an explosive scene.
The key point is the bursting event itself, not just smoke or brightness.

Use it for explosion, blast, detonation, or a clearly named explosive scene.
It may include sparks or debris as long as the person keeps the central idea of explosion.
If the main focus is fire or smoke rather than explosion, first reconsider scoring-input/contents/Fi.

Ex and scoring-input/contents/Fi may coexist visually, but they are not the same code.
Ex requires an explosive event; Fi requires fire or smoke as the main content.
Do not use Ex for a mere sense of energy or motion.
