Defined in:

Overview

Y-coordinate calculator for the compartments of an element box: header text, header divider, attribute rows, operation rows, enum literals, tagged-value rows.

Owns its own coordinate math; the rest of Elements only reads header_first_y, divider_y, attr_first_y, etc. Construction takes the bounds, font size, line counts, and per-region offsets from the theme.

Extracted from Elements.rb to keep each concern in one place (MECE). Element rendering reads these values; coordinate math changes don't ripple into rendering.
