/* SwissTechFlow — swisstechflow.ch
   Direction: Swiss technical document. Hairline rules, monospaced labels,
   tabular figures, generous white space, one red accent.
   No dark-mode toggle by design: leftclick.ai auto-flips to dark when the OS
   prefers dark, which is the whole reason that site read as "too dark". The
   paper here is a warm stone rather than near-white, and three of the eight
   blocks are dark bands — deliberately heavier than the first version. */

/* The entry stagger is an ANIMATION, not a delayed transition, and that is the
   whole point. It used to be a transition with transition-delay up to 1.1s —
   which stayed applied forever, so a circle took up to 1.1s to fade back out of
   its hover colour after the cursor had already left. Adding the delay reset to
   :hover only fixed the way in, never the way out. An animation cannot leak into
   the hover transition at all, so the circle now tracks the cursor exactly.
   animation-fill-mode is `backwards`, not `both`: with `both` the animation
   would keep owning `transform` after it finished and the hover scale would
   never apply. */
