/* ============================================================================
   beatvest slides
   The component layer for presentations.

   No colour, no font size and no spacing value is written here. Everything
   comes from dist/beatvest-tokens.css, generated from DESIGN.md.

   The two exceptions are the motion constants below. The DESIGN.md linter
   rejects custom top-level keys, so durations and the easing curve cannot live
   in the token file. They are declared once, here, and never repeated.

   Load order matters:
     dist/beatvest-fonts.css
     dist/beatvest-tokens.css
     dist/beatvest-type.css
     css/beatvest-slides.css   <- this file
     dist/beatvest-utils.css   <- last, so spacing utilities win
