/* ============================================================================
   HiveSystem — landing stylesheet  (landing/assets/site.css)
   ----------------------------------------------------------------------------
   Plain CSS. No framework, no bundler, no npm step. The page must render the
   same opened straight off the filesystem (file://) and served from a web root,
   so nothing here depends on a build or on an absolute origin.

   WHERE THE VALUES COME FROM
     Every colour, radius, duration, ease and type step below is the REAL
     product token, read out of frontend/src/styles.css (design tokens v0.5.0).
     The approved mockup (landing/mockup-v2-modern.html) carried hand-copied
     near-misses; those copies were not trusted and are not reproduced.

   WHAT THIS FILE DELIBERATELY DOES NOT DO
     - No CDN, ever. The typeface is self-hosted from ../fonts/ because an
       on-prem / air-gapped install has no route to a CDN — see the comments in
       frontend/index.html:15-17 and frontend/src/styles.css:24-30.
     - No drop shadow for depth. Depth is the hairline (--line / --line-strong)
       only, and a card "lift" is translateY + border-strong, never a shadow
       (design law rule 18). The only elevation the product allows is
       --shadow-pop on overlays, and a landing page has no overlays.
     - No gradient other than --gradient-accent, and that one is decorative:
       exactly one word in the hero. Never a button, never a card, never data
       (rule 16).
     - No text label on a chart series fill (rule 11). The data bars in the
       hero frame and in the wide bento card carry no labels at all.
     - No raw colour in the markup: index.html only ever names a custom
       property or a class. Raw values live here, once, in :root.
   ========================================================================= */

/* --- 1. Self-hosted Persian typeface -----------------------------------------
   IRANYekanX (FaNum variable build) is the product's own licence-held face.
   It is a VARIABLE font: the wght axis runs 100..1000, so no static weight is
   invented — matching frontend/src/styles.css:31-40, which declares the axis
   range rather than a fixed weight. The two url() paths are relative to this
   stylesheet (assets/ -> ../fonts/), which is what keeps the page working both
   from disk and from a web root.
   Persian needs kerning + contextual alternates for correct letter joining.  */
