/* Smartwatch Export Site — V1 shared styles
   Design language grounded in a REAL competitor audit, not invented from scratch.
   Source: outputs/competitor-visual-audit/audit-report.json (2026-09-13),
   5 real Shenzhen smartwatch B2B sites (Starmax / Galax / iSmarch / IWO / Naviforce)
   captured live via headless Chrome + CDP, computed styles extracted programmatically.

   Findings applied here:
   - White page background: 5/5 sites.
   - Black (#000000) top nav bar: 4/5 sites.
   - System/sans-serif body fonts (Open Sans, Source Sans Pro, system-ui): 5/5 sites.
   - Solid black CTA buttons: 4/5 sites (one red, one blue outlier — we keep black as
     the dominant pattern and add a single accent color for links/highlights only).
   - Hero is dominated by large real product photography, not a text-only gradient
     panel — all 5 sites. Our hero therefore reserves a real image slot, and until
     real product photos exist it is honestly labeled as a placeholder (no fake
     photography, per this workspace's content guardrails). */
