/* =============================================================================
   Avielon Studio · services.css
   Shared page-level styles for the service-page template (Tasarım / Yazılım).
   Loaded AFTER tokens.css + site.css, BEFORE the per-page sheet (tasarim.css /
   yazilim.css). Holds only what is identical across both service pages:
   section scaffolding, the service-list + feature component, the work-card grid,
   the FAQ accordion, the closing CTA band, and the scroll-reveal.

   Page "signature" styles (the two-column hero + corner frame, the value
   pillars, the process track/timeline, the compare panels, the tech grid) live
   in the per-page sheet, because only one of those ever loads on a given page.

   Note — a few trivially divergent values were normalised here to a single
   source of truth (feature gap .45→.5rem, feature max-width 60→62ch, cta lead
   54ch). The visual delta is sub-pixel; flag if you'd rather keep them split.
