   ЗАЯВКА НА ХАКАТОН — standalone V2 page (site-v2/apply.html), NOT part of
   the .yh-app scene system, so no .yh-app scoping needed here (same as V1's
   own apply.html — a real navigable page, not an embedded Tilda block).

   Visual language ported from V1's css/style.css `.sheet-*` component
   (read-only reference — V1 itself was never touched) because the customer
   asked to "pull the actual application form from version 1", just with
   the new question set from her document, grouped into her own 6 blocks
   instead of V1's 7 steps. Copied here as a fresh, V2-owned file rather
   than linking V1's shared stylesheet, so V1 stays completely untouched
   and V2 doesn't depend on a file it doesn't own.

     THIRD fix (same day, "первая строчка состоит из 2 линий" — a SECOND
     attempt at this, using background-position to shift a plain
     repeating-linear-gradient, still produced a genuine extra
     mispositioned line — confirmed via an isolated Playwright test
     sweeping background-position values: this specific combination
     (box-sizing:border-box on this page + a border-bottom + a non-zero
     background-position-y ≥ 7px) reliably makes Chromium paint a SECOND
     copy of the line, shifted 7px off — a real rendering bug in that
     combination, not a math error). Fixed by not using background-
     position at all: the padding offset is baked directly into the
     gradient's own color-stop list instead (one 30px-tall tile, opaque
     only across its own 8px-9px band), leaving background-position at
     its default (0, always clean in the same test) — mathematically the
     same repeating pattern, verified line-for-line clean afterward. */
