First override→inheritance migration, proving the pattern. Replace 4
add_theme_color_override("font_color", ...) calls with theme_type_variation:
cost→LabelMuted, hint→LabelDisabled, title→LabelTitle, flavor→LabelSecondary.
Widgets now inherit the colour from ui_theme.tres instead of hand-setting it.
Value-preserving (variations carry the same token colours). Render-verified on
plum via tech_tree_proof — cost labels render the muted colour correctly, tree
unchanged. Remaining accent-param labels (_make_pill/_make_section) stay as
overrides (dynamic colour). The redundant text.primary overrides (= Label
default) are a separate delete-pass.
