/**
 * TMT Culture Circle.
 *
 * Every selector is namespaced under .tmt-culture-circle so nothing here can
 * reach the theme, and the button resets are written with an element selector
 * (`button.tmt-culture-circle__item`) so a theme's global button styling cannot
 * outrank them. They stay below the three-class selectors Elementor generates
 * from the panel, which must keep winning.
 *
 * Geometry contract:
 *   Panel writes  --tmt-cc-ring-max, --tmt-cc-circle-pref, --tmt-cc-circle-min,
 *                 --tmt-cc-circle-gap, --tmt-cc-center-gap
 *   Script writes --tmt-cc-size, --tmt-cc-radius, --tmt-cc-circle,
 *                 --tmt-cc-center-max
 *   PHP writes    --tmt-cc-angle (per item)
