A Coordinate is the fixed ordered pair identifying the horizontal spread line and vertical spread row occupied by a card within a designated matrix spread of the Destiny Cards system. Expressed as the ordered pair [Line, Row] - such as [Jupiter, Uranus] or [Crown, Jupiter] - it deterministically specifies the exact two-dimensional cell position of a card archetype within the 52-card layout (comprising the primary 49-card planetary grid and the three-card Crown tier).
Interpretive Meaning:
A Coordinate represents the functional intersection of two distinct planetary currents shaping a card's expression at a given stage of quadration. The horizontal line dictates the mode of action and transmission, while the vertical row grounds that expression within a specific arena of experience and development.
