/* ============================================================================
   help.css — the Help Center shell and its content components (HC-2, D-HC-06)

   Replaces the 330-line <style> block that lived inside templates/help/base.html.
   Loaded from that template AFTER style.css, so it wins on ties; theme.css is
   already in scope via includes/head_meta.html.

   COLOUR RULE: every value here resolves to a theme.css token. The help pages
   introduced eight ad-hoc hexes (#fafafa, #eee, #f9f9f9, #f39c12, #d73502,
   #2c5a3e, #e5e5e5, #666) and used the light brand green #71c55d as *text* on
   white, which fails AA — that green is a FILL colour. If a page needs a colour
   that is not a token, that is a finding for HC_PLAN, not a licence to add a hex.
   The only literals below are rgba() of tokens already in the palette (the brand
   green / blue / amber at alpha, exactly as base_landing.html uses them), named
   once as --help-* variables so they are not re-typed per rule.

   THE COMPONENT SET — HC-4/5/6 write markup against THESE names. Do not invent
   parallel classes; extend these:

     Shell      .help-container  .help-sidebar  .help-content
                .help-breadcrumb .help-header   .help-footer
     Content    .hc-eyebrow      small-caps dark-green label above a heading
                .hc-card         white card, thin line, one soft shadow
                .hc-grid         auto card grid (+ .hc-grid--2 / --3)
                .hc-callout      aside (+ .hc-callout--info / --warn / --tip)
                .hc-steps        ordered list, green numerals
                .hc-figure       captioned block (figure.hc-shot = screenshot,
                                 D-HC-03 — keep that name)
                .hc-video        16:9 responsive embed wrapper
                .hc-table        data table
                .hc-cta          green pill button

   LEGACY ALIASES (bottom of file): the pre-HC-2 pages use .help-card (260
   occurrences), .help-card.info/.success/.warning, .help-article, .contact-info,
   .contact-item and .role-badge. They are aliased onto the components above so
   those pages inherit the brand today. HC-4/5/6 rewrite them page by page; the
   alias block is deleted with the last one.
