   Castillo Carpet Service – styles

   Order (general → specific; later blocks may override earlier ones):
     1. Tokens        – colors, fonts, spacing (change the look here)
     2. Base          – reset and element defaults
     3. Layout        – container, section spacing, section titles
     4. Components    – reusable pieces (button, carousel, lightbox, …)
     5. Sections      – one block per page section, in page order
     6. Utilities     – motion / accessibility helpers

   Naming: BEM  →  .block, .block__element, .block--modifier
   Breakpoints (kept next to each block, desktop-first):
     1100px  large tablet · 999.98px  tablet · 700px  phone
