/* ============================================================
   FEATURE CHIPS — Display-only feature labels and interactive
   feature/add-on selectors.

   Two distinct primitives:

   A. FeatureChip (display-only)
      Shows what a room or booking already includes.
      Read-only. Quiet. Informational.

   B. FeatureSelector (interactive)
      Toggleable chips for "Select the features that matter
      most to you" screens. Tappable. Clear selected state.

   USAGE (display-only):
   <div class="feature-chip-group">
     <span class="feature-chip">
       <svg class="feature-chip__icon">...</svg>
       King Bed
     </span>
     <span class="feature-chip">
       <svg class="feature-chip__icon">...</svg>
       Ocean View
     </span>
     <span class="feature-chip">Pet-Friendly</span>
   </div>

   USAGE (interactive selector):
   <div class="feature-selector-group">
     <p class="feature-selector-prompt">Select the features
       that matter most to you</p>
     <div class="feature-selector-grid">
       <button class="feature-selector" aria-pressed="false">
         <svg class="feature-selector__icon">...</svg>
         <span class="feature-selector__label">1 King Bed</span>
       </button>
       <button class="feature-selector feature-selector--selected"
               aria-pressed="true">
         <svg class="feature-selector__icon">...</svg>
         <span class="feature-selector__label">Private Balcony</span>
       </button>
     </div>
     <button class="feature-selector-overflow">
       +3 more features
     </button>
   </div>

   RULES:
   - NO emojis. Icons are line-art SVGs (Lucide or custom).
   - NO border-radius. Sharp corners. Always.
   - NO blue. Selected state uses brand primary.
   - Icons are optional. Chips work with or without them.
   - Interactive selectors must meet 44px min touch target.
   - Overflow chip is a ghost-style trigger, not a count badge.

   D. ADD-ON CARD — For priced extras (breakfast, parking, etc.)
   ================================================================

   Two modes:

   1. Display-only (informational) — shows what's already on a
      booking. Uses a <div>, no cursor, no hover, no press state.

   2. Interactive (selectable) — toggleable add-on on a selection
      screen. Uses a <button> with aria-pressed.

   USAGE (display-only):
   <div class="addon-card addon-card--display">
     <div class="addon-card__content">
       <svg class="addon-card__icon">...</svg>
       <div class="addon-card__text">
         <span class="addon-card__name">Breakfast Package</span>
         <span class="addon-card__description">Daily buffet for 2 guests</span>
       </div>
     </div>
     <div class="addon-card__price">
       <span class="addon-card__amount">$45</span>
       <span class="addon-card__unit">/ night</span>
     </div>
   </div>

   USAGE (interactive):
   <button class="addon-card" aria-pressed="false">
     <div class="addon-card__content">
       <svg class="addon-card__icon">...</svg>
       <div class="addon-card__text">
         <span class="addon-card__name">Breakfast Package</span>
         <span class="addon-card__description">Daily buffet for 2 guests</span>
       </div>
     </div>
     <div class="addon-card__price">
       <span class="addon-card__amount">$45</span>
