/* =================================================================
   SYNTRIX STUDIO — GLOBAL + HOMEPAGE STYLESHEET
   -----------------------------------------------------------------
   Shared across every page: theme tokens, glassmorphism, buttons,
   navbar, footer, floating contact menu, scroll animations — plus
   homepage-only pieces (hero terminal, stats counters, the "working
   flow" steps, testimonial carousel). The site is hardcoded to a
   single dark theme — there is no light-mode toggle.

   Careers-page-only styles (the application form, file upload,
   hiring-process numbers, status modal) live in careers.css instead,
   loaded only on careers.html, per the requested modular split.

   👉 TO RESTYLE THE WHOLE SITE: edit the variables in section [1].
   Everything else references those variables, so changing a hex
   code there updates every page at once — including careers.html,
   since careers.css reuses the same variable names.
   ================================================================= */

/* -----------------------------------------------------------------
   [1] THEME TOKENS — hardcoded, single dark palette (no toggle)
   -----------------------------------------------------------------
   These are the exact tokens from the Syntrix Studio design system.
   👉 TO RESTYLE THE WHOLE SITE: edit the values here only.

   The second block below (--bg, --cyan, --blue, etc.) are internal
   aliases. Every component class in this file — and every inline
   `style="color:var(--cyan)"` across ALL pages — points at those
   alias names. Keeping them means the whole site (including pages
   not touched in this update) repaints with the new brand colors
   automatically, with nothing else to find-and-replace.

   <head> (see any page's <head>), which only runs if JS is actually
   executing. If a script is ever blocked, 404s, or fails for any
   reason, <html> never gets "js", these rules never apply, and every
   [data-reveal] element is fully visible by default instead of
   silently stuck at opacity:0 forever. Content should never depend
   on JavaScript to simply be visible — only the animation should.
