/* =========================================================
   v3.7.3 — PARENT-THEME BUTTON HARDENING + OVERFLOW GUARD
   On LIVE, TenWeb/Elementor injects `.elementor-kit-50 button`
   (specificity 0,1,1): padding:12px 24px / min-width:auto /
   accent-blue bg / 1px border / radius:3px / appearance:button.
   That BEATS our plain `.tct-carousel__dot|__arrow` (0,1,0), so
   the dots render as ~50x26px blue rectangles; as flex items
   with min-width:auto they floor at min-content (~50px) and the
   7-dot row overflows the mobile carousel => +4px horizontal
   page scroll at 390px. We re-declare with `body.tct-home`
   (0,2,0) + !important and zero every leaked property. This is
   the single source of truth for dot/arrow styling.
   (A bare local preview without WordPress does NOT reproduce
   this — only the live parent theme does.)
