/* ========== MOBILE MENU ==========
   Slide-in panel from the right that holds a flattened version of the entire
   navigation. Designed for the practice's elderly patient population: big
   touch targets (minimum 48px tall), generous vertical spacing, clear visual
   distinction between section headers and sub-items, and high-contrast CTAs
   at the bottom that thumb naturally reaches.

   Hidden by default. Activated when JS adds .open to the panel and the
   backdrop. The panel is on top (z-index 200); the backdrop sits below it
   at z-index 199 and dims/blocks the rest of the page.

   Only relevant below ~900px (where .menu-toggle becomes visible). Above
   that, both panel and backdrop stay hidden regardless of state. */

/* ========== PAGE FADE-IN ==========
   In the single-file prototype, .page elements were stacked in one DOM and

   and keep the entrance animation for a soft fade-in on each real navigation. */

/* ========== WHOLE-CARD CLICK TARGETS ==========
   In the prototype, certain cards (service rows, physician cards, location
   cards) were entirely clickable via a JS data-page handler. In the deployed
   multi-page site we replace that with a "stretched link": an invisible
   anchor inside the card whose ::after pseudo-element overlays the whole
   card. This avoids nested anchors (some cards contain a tel: link) while
   still letting the user click anywhere on the card to navigate.

   Cards opt in by adding the class `card-clickable`. The stretched link is
   <a class="card-stretched-link"> placed as the first child of the card.

   Important: the card must be position:relative for the ::after overlay
   to size to it. Nested links (e.g. tel:) get position:relative + z-index:1
   so they remain independently clickable above the overlay. */

/* ========== ACCORDION (FAQ) ==========
   Used for Q&A sections where a long list of questions would overwhelm if
   all answers were shown at once. Each question is a button; clicking
   reveals the answer below. Multiple can be open simultaneously (we
   intentionally don't enforce single-open — patients reading the FAQ
   may want to compare two answers).

   Accessible: each button has aria-expanded, each panel has aria-hidden,
   answers are real DOM (visible to search engines and screen readers
   even when collapsed, just hidden visually).

   Markup pattern:
     <div class="accordion">
       <div class="accordion-item">
         <button class="accordion-trigger" aria-expanded="false">
           <span>Question text</span>
           <span class="accordion-icon" aria-hidden="true">+</span>
         </button>
         <div class="accordion-panel">
