/* ============================================================================
   JuHost — standalone tools stylesheet  (v1.0.0)
   ----------------------------------------------------------------------------
   A dependency-free, dark brand skin for the JuHost utility pages that live on
   OTHER servers than the marketing site:

     · Speedtest  (LibreSpeed)      e.g. hknt.st.juhost.com
     · Looking Glass (Telephone LG) e.g. hknt.lg.juhost.com

   Those hosts are per-facility probe boxes — they must NOT carry a copy of the
   site build. So they link this ONE file over the wire:

       <link rel="stylesheet" href="https://juhost.com/brand/juhost-tools.css?v=1.0.0">

   It ships from juhost-new/public/, which Vite copies verbatim into dist/, so a
   normal site release publishes it at /brand/juhost-tools.css. Nothing else is
   needed on the probe box: no Bootstrap, no jQuery UI kit, no font files, no
   logo image (the mark is inline SVG in each page).

   ⚠ Cross-origin fonts: the @font-face files below are fetched by a document on
   a DIFFERENT origin, so the CORS gate applies to them. juhost-new/public/
   .htaccess sends `Access-Control-Allow-Origin: *` for /fonts/ and /brand/ —
   keep that rule or the pages silently fall back to system sans.

   Token source of truth ........... juhost-new/tailwind.config.js
   Global CSS reference ............ juhost-new/src/index.css
   Chrome reference ................ juhost-new/src/components/layout/*
   Sibling implementation .......... whmcs/26juhost/css/custom.css
   Bump the ?v= in BOTH pages when this file changes.
   ========================================================================== */

/* ==========================================================================
   1. Brand fonts — self-hosted on juhost.com, mirrored from src/fonts.css
   Paths are relative to THIS file (/brand/), so they resolve to /fonts/ on the
   site origin regardless of which probe host loads the sheet.
   Only the weights the tool pages actually use are declared (Inter 400/500/600,
   Space Grotesk 600/700, IBM Plex Mono 400/500) — the woff2 files are the same
   ones the site preloads, so a visitor arriving from juhost.com gets them warm.
