Spell Formula (and Formulas)

A Spell Formula is the stabilized declaration structure a caster records in their Grimoire. In current canon, formulas are written as:

Intent -> School -> Glyph -> Scale -> Tags

When a Formula is cast in danger, it is resolved through Shape the Matrix.

Legacy Function/Medium/Modifier notation can still appear in older notes; treat those as archival component syntax and map them to the current declaration format when used at the table.
