/* The three steps of "How it works", animated in CSS alone — no script runs on the page
   (spec 4.10). A packet crosses the rail from glyph to glyph; the hear-waves radiate
   while it rests on stage one, the solve-card lights while it rests on stage two, and
   the fix-ring expands when it reaches stage three. One 9 s cycle, looped. Under
   prefers-reduced-motion every animation stops and the section is the three static
   cards it is without them.

   The rail spans the first and last GLYPH centres, not the card centres: each glyph
   sits at the card's left padding (24px) plus its own half width (14px), and the cards
   are an equal third of the grid minus its two 20px gaps. `.flow` is flow-root so the
   grid's margin-top stays inside it and the rail's top can be the glyph centre:
   24px margin + 24px card padding + 14px = 62px. */
