/*
  The approved `/your-claims` body layer, ported rule for rule from the reference build
  (`ndic-reference/css/public/your-claims-revamp.css:167-527`).

  WHAT THIS IS FOR. The approved page presents the filing guide as a collapsible disclosure with the
  claim form permanently visible beneath it. This build had a two-tab bar instead, with the form in a
  panel carrying `hidden` — so the form was unreachable without JavaScript, and a visitor who came to
  file a claim saw a wall of instructions and no form.

  ONLY THE `yx-*` RULES ARE HERE. The source file also carries the `.px-page .sc-*` form layer, and
  54 of those 58 rules are already byte-identical in `px-shared.css`; copying them would be the
  duplicate-that-drifts this project has been bitten by twice. The four it does not carry
  (`.sc-claim-other`, `.sc-required`, and two for `.sc-field--upload`) are not emitted by this build —
  three of them style the file-upload field, which does not exist here yet.

  THIS LAYER NEEDS `.px-page`. Every rule below reads `--px-*` custom properties, and those are
  declared on `.px-page` and nowhere else. `claim_forms_hub` therefore wraps its body in one, exactly
  as `policy_prose` does. See core-public-site-technical § "`.px-page` is a token scope".

  The six rules the first pass missed, and the one that mattered visibly.

  `.yx-form-section .yx-disclosure` caps the guide at the same 920px measure as the form beneath it
  (`--px-form-max`). Without it the "How to file" panel ran the full container width while the form
  below sat at 920px — the mismatch that made the page look wrong. It lives at line 539 of the
  reference sheet, past the line-527 boundary the first extraction stopped at, which is what happens
  when a port is taken by line range instead of by rule.

  The other five are the ones px-shared.css does not carry: the anchor scroll offsets, the
  conditional "other" textarea's spacing, the required asterisk's colour, and the two that give the
  passport upload its column shape.
