/* =============================================================================
   ACRONIS — Palette & Design Tokens (single source of truth for the Acronis brand)
   =============================================================================
   Scope   : font, color palette and semantic tokens.
   Loaded  : by the Acronis templates (head_extra block).
   Pairs   : component styles (.ac-*, .acm365-*) live in
             app/static/css/tailwind-input.css under the ACRONIS sections.

   SOURCE OF THE VALUES BELOW — two official sources, no guesswork:
     1. "Acronis Logo Usage Guidelines" (Acronis, dl.acronis.com/u/pdf/
        acronis_guidelines.pdf), page 6 "COLORS", which is the governing document:
           Navy Blue  Print PANTONE 282C / Web & UI #00204D   <- primary
           Blue       #4875B3      Steel #9297A1      Green #9BC225   <- secondary
        Page 10 specifies the corporate typeface: Open Sans.
     1b. The brand style guide at logo.acronis.com (updated 15 Jun 2026) supersedes that PDF:
        typeface is the Acronis Cyber family (variable, weight 200-800), and the blue shades are
        #3764AF, #173E7E, #387DC0, #83D0F5, #73ACDD, #D4E5F7 (tokens --ac-guide-blue-*).
     2. Live acronis.com measured with Playwright (Oct 2026) for the accents the
        current product UI actually ships, the same method used for redhat.com and
        cloud.google.com:
           navy   rgb(0, 32, 77)    #00204D   (matches the guide exactly)
           green  rgb(35, 225, 114) #23E172   CTA accent
           blue   rgb(0, 101, 227)  #0065E3   button fill
           blue   rgb(64, 139, 234) #408BEA
           link   rgb(38, 104, 197) #2668C5
           body   rgba(36, 49, 67, 0.9)
           font   "Acronis Cyber", sans-serif   radius 8px
        app/static/img/svg-icon/Acronis-logo.svg and Acronis-symbol.svg fill with
        #00204D, confirming the navy.

   WHAT WAS WRONG BEFORE
   The old --ac-* block kept the correct navy (#00204D) and the correct green
   (#9BC225), but invented five blues that appear in no Acronis asset
   (--ac-additional-blue #173E7E, --ac-accent-blue #5BA3E8, --ac-ultra-light
   #A8E0FF, --ac-secondary-blue #73ACDD, --ac-light-blue #D4E5F7) and used them
   for whole page gradients. It also carried --ac-red #D20A10, --ac-orange #FF7300
   and --ac-yellow #F59B00, which are not Acronis brand colors. Worse, the GEO and
   FAQ sections on every Acronis page were configured with 'color': 'blue', which
   resolved to the generic .sx-blue (#1D4ED8) — a Tailwind blue, not Acronis navy.
   All of that is why the Acronis pages read as "no defined palette".

   Icons: the official marks in app/static/img/svg-icon/ (Acronis-logo*.svg, Acronis-symbol*.svg,
          Acronis_Cyber_Protection*.svg) identify the BRAND. Capability, step and benefit glyphs are
          the official duotone icon library from the acronis.com platform pages, one SVG per icon in
          app/static/img/svg-icon/acronis-icons/<id>.svg (linear gradients #70B1FF to #005CCD, as
          shipped by acronis.com). Vendor logos (Microsoft, Google, AWS...) stay Bootstrap glyphs.

   NEVER hard-code a hex value in .ac-* component rules; use a token from here.

/* ---------------------------------------------------------------------------
   1. FONT — "Acronis Cyber" (the current brand face, brand style guide logo.acronis.com/typo,
      updated 15 Jun 2026) is self-hosted as ONE variable font (weight axis 200-800: Ultra Light
      to Ultra Bold) from app/static/fonts/acronis/Acronis_Cyber_VF/. The 2014-era logo guide specifies Open Sans as the
      corporate face, and Open Sans is also self-hosted (fonts/open-sans/) for the
      logo lock-up and long-form copy, matching the guide's Light/Regular/Bold/
      ExtraBold assignment. Both are declared here so no Acronis page ever falls
      back to a generic system font.
