/* ===================================
   HIERARCHICAL CLASS SYSTEM - GUIDE
   ===================================

   This CSS uses a hierarchical class system to make styling
   easier to maintain and update site-wide.

   CONCEPT:
   Instead of creating standalone classes with all properties,
   we use BASE CLASSES + MODIFIER CLASSES.

   EXAMPLE:
   Instead of: <div class="chat-card">
   You can use: <div class="box box-chat">

   BENEFITS:
   1. Change all boxes at once by editing .box
   2. Smaller, focused modifier classes
   3. Easy to create new variants
   4. Clear, predictable naming

   ---

   BOXES & CARDS - Base: .box
   ---
   .box               = Base box (border-radius, transition, padding)
   .box-chat          = White background, border, subtle shadow
   .box-button        = Primary colored, no border
   .box-section       = Large content sections with extra padding
   .box-info          = Highlighted background for info/notices
   .box-score         = Centered content for stats/scores
   .box-item          = List item with flex layout

   Usage: <div class="box box-chat">...</div>

   ---

   BUTTONS - Base: .btn
   ---
   .btn               = Base button (border-radius, font-weight, transition)
   .btn-primary       = Primary action (blue background)
   .btn-secondary     = Secondary action (white with border)
   .btn-card          = For use in cards/lists
   .btn-minimal       = Subtle, transparent background
   .btn-danger        = Destructive actions (red)

   Usage: <button class="btn btn-primary">Click me</button>

   ---

   CONTAINERS - Base: .container-page
   ---
   .container-page    = Base container (auto margin, full width, padding)
   .container-narrow  = Max width 700px (forms, auth)
   .container-standard = Max width 1200px (most content)
   .container-full    = Full width, no max
   .container-centered = Flex centered, min-height 60vh

   Usage: <div class="container-page container-narrow">...</div>

   ---

   LISTS - Base: .list-clean
   ---
   .list-clean        = Removes default list styling
   .list-items        = Vertical stack with gap
   .list-grid         = Grid layout with gap
   .list-grid-2       = 2-column auto-fit grid
   .list-grid-3       = 3-column auto-fit grid

   Usage: <ul class="list-clean list-items">...</ul>

   ---

   TEXT UTILITIES
   ---
   Colors:
   .text-primary-color   = Main text color
   .text-secondary-color = Secondary text color
   .text-light-color     = Light/muted text
   .text-brand           = Brand primary color
   .text-accent          = Accent color

   Sizes:
   .text-sm, .text-lg, .text-xl

   Weight:
   .text-bold, .text-normal

   Usage: <p class="text-brand text-lg">...</p>

   HOW TO CREATE NEW VARIANTS:
   ---
   Need a new box type?
   1. Add a new class like .box-myvariant
   2. Only define what's DIFFERENT from .box
   3. Use it with: <div class="box box-myvariant">

   Example:
   .box-warning {
       background-color: var(--warning);
       color: var(--text-white);
       border: 2px solid var(--accent);
   }

   Usage: <div class="box box-warning">Warning message</div>
