/* Home: «Как это работает» (src/js/home/how-it-works.js) and «Лента покупок» (src/js/home/live-feed.js).
   Owner: how-live. Same light language as the rest of the page: white islands on the paper, Alumni Sans 900 upright
   (+ .oblique) for numerals, Golos Text for everything else, the brand blue for state. The blocks add no outer
   margins (the page grid in home.css spaces them). Motion: «Как это работает» lights its steps up once when it is
   first seen (plus one small move of a card's icon under the pointer); the live feed's own motion is described at
   its rules below. None of it under prefers-reduced-motion (base.css resets durations; the modules do not start
   theirs either). */

/* ==========================================================================
   Как это работает: the four steps in one row, as before — what changed is inside the card. Each island carries its
   mark in a filled disc on the left and, beside it, the numeral over the title over one sentence (owner 06.10.2026,
   from a reference she sent: «слева логотип Стима… 01, вход через Steam… чтобы оно не терялось на этом фоне»).

   What changed and why: the old cards carried a 28px line glyph in the top corner and a hairline border with no
   shadow, so on the paper background they read as four faint rectangles — the block had no anchor anywhere. The
   dark disc gives every step one, and the border + soft shadow lift the island off the paper. The thin arrow from
   card to card stays, now level with the discs it runs between.
