/* ===================================================================
   Yandere Together — site styles

   Structure follows the conventions of a game-community site: sticky
   header with horizontal nav, wide hero banner, banded sections, card
   grids, multi-column footer.

   The palette is sampled from the logo rather than chosen alongside it:
   rose #F0A0B0 is the heart, crimson #A01030 and maroon #500010 are its
   shading and outline, blade-grey #B08090 is the knife steel and doubles
   as the secondary ink.

   Type is Poppins, self-hosted from the same .ttf files the launcher and
   the in-game HUD embed, so all three surfaces are set in one face.

   The page commits to one visual world, so the tokens are locked rather
   than themed; both toggle states resolve to the intended dark ground.
