 * @since 1.14.2 — Cascade defense against Elementor kit-level link styles.
 *
 * Same root cause as the PSC sibling stylesheet: the CTA is an <a>, so it's
 * hit by Elementor's `.elementor-kit-XX a { color: ... }` (specificity 0,1,1)
 * which outranks single-class selectors like `.eiasm-ppb__cta--primary`
 * (0,1,0) and turns the white button text teal-on-teal. Same `.elementor a`
 * reset for `box-shadow` and `text-decoration`.
 *
 * Fix: scope under `.eiasm-ppb` AND chain modifier with base class. Base
 * rules become (0,3,0), interaction rules (0,4,0) — beats today's override
 * and any future Site Settings → Theme Style → Buttons configuration.
 * No `!important`; override ladder preserved.
 *
 * Do NOT "simplify" this back to single-class selectors. See post-launch
 * track §3.1 — and keep this in sync with programme-summary-card.css.
