   LYLA CSS CHEAT SHEET (MINIMAL – FOR MAKING NEW SECTIONS)
   ---------------------------------------------------------

   USE THESE CLASSES TO BUILD:
   - new sections
   - new section headers
   - new grids (rows of boxes)
   - new cards (white boxes)
   - CTAs (buttons)

   ---------------------------------------------------------
   1. SECTION STRUCTURE
   ---------------------------------------------------------

   .section
     - A standard block of vertical spacing.
     - Use this for EVERY new section.

     HTML:
       <section class="section">...</section>


   .section-alt
     - Same as .section but with a light tinted background.
     - Great for visual separation.

     HTML:
       <section class="section section-alt">...</section>


   .section-header
     - Proper spacing & width for section title + description.

     HTML:
       <div class="section-header">
         <h2>Title</h2>
         <p>Description text.</p>
       </div>


   ---------------------------------------------------------
   2. GRID LAYOUTS (rows of cards/boxes)
   ---------------------------------------------------------

   .grid-2
     - Two columns on desktop → one on mobile.

     HTML:
       <div class="grid-2">
         <div class="card">Box 1</div>
         <div class="card">Box 2</div>
       </div>


   .grid-3
     - Three equal-sized columns (becomes one column on mobile).

     HTML:
       <div class="grid-3">
         <div class="card">Box 1</div>
         <div class="card">Box 2</div>
         <div class="card">Box 3</div>
       </div>


   ---------------------------------------------------------
   3. CARDS (white boxes)
   ---------------------------------------------------------

   .card
     - White box with rounded corners + shadow.
     - Use this for ANY content box.

     HTML:
       <div class="card">
         <h3>Box Title</h3>
         <p>Info text...</p>
       </div>


   .feature-card
     - Optional: extra spacing/text styling inside a card.

     HTML:
       <div class="card feature-card">
         <h3>Feature Title</h3>
         <p>Some text...</p>
       </div>


   ---------------------------------------------------------
   4. TEXT HELPERS
   ---------------------------------------------------------

   .eyebrow
     - Small uppercase label above a title.

     HTML:
       <p class="eyebrow">Label</p>


   ---------------------------------------------------------
   5. BUTTONS (optional for section CTAs)
   ---------------------------------------------------------

   .btn .btn-primary
     - Electric-blue main button.

     HTML:
       <a class="btn btn-primary">Click me</a>

   .btn .btn-ghost
     - Transparent bordered button.

     HTML:
       <a class="btn btn-ghost">Learn more</a>


   ---------------------------------------------------------
   6. MOST USEFUL PATTERN (copy this often)
   ---------------------------------------------------------

   <section class="section">

     <div class="section-header">
       <h2>My New Section</h2>
       <p>Short description for this section.</p>
     </div>

     <div class="grid-3">
       <div class="card feature-card">
         <h3>Card One</h3>
         <p>Some text...</p>
       </div>

       <div class="card feature-card">
         <h3>Card Two</h3>
         <p>Some text...</p>
       </div>

       <div class="card feature-card">
         <h3>Card Three</h3>
         <p>Some text...</p>
       </div>
     </div>

   </section>
