/* ----- §2.1 Sticky/condensed mobile CTA -----
   Slim persistent bar on mobile only; hidden on desktop. Anchors
   the primary low-commitment action so it's always one tap away
   on long pages. Pages opt in by including the markup; CSS handles
   visibility.
   Markup pattern (place once near end of <body>):
     <div class="sticky-cta" data-screen-label="Sticky CTA">
       <button class="btn btn-primary" type="button" data-quote-trigger>
         Find your robot <span class="arrow">→</span>
       </button>
       <a class="sticky-cta-phone" href="tel:+61406607399"
          aria-label="Call Perth Robots">
         <i data-lucide="phone" style="width:18px;height:18px;"></i>
       </a>
     </div>

/* ----- §5 Split hero (no text-only heroes) -----
   Mirrors the homepage hero's two-column treatment: text-left,
   image-right at ≥1024px, stacked on mobile. Opt in by wrapping
   the hero content in .lp-hero-grid with .lp-hero-text + .lp-hero-media.
   The media column is decorative — alt text describes the unit /
   environment, never an implied client deployment.
   Markup pattern:
     <section class="lp lp-hero lp-hero-split">
       <div class="wrap">
         <div class="lp-hero-grid">
           <div class="lp-hero-text">…hero copy…</div>
           <figure class="lp-hero-media">
             <img src="public/images/fleet/s5-hero.webp"
                  alt="Cenobots S5 autonomous sweeper"
