SmartPharma360™ — Brand Asset Pack
==================================
Brand colours: Navy #0a0e24 / deep #05060f · Gold #c9a44a

/favicon      Browser favicons (.ico multi-size, 16/32/48 PNG) and the
              monochrome Safari pinned-tab SVG (tint #c9a44a).
/pwa-icons    Android/iOS home-screen icons 64–512px, maskable variants
              (192/512) and the web app manifest that references them.
/og-images    1200x630 social preview art used for Open Graph and Twitter
              cards: home, platform, whatsapp, security, demo.

Social previews are served with a ?v= version query. When artwork is
replaced, bump OG_ASSET_VERSION in src/lib/og.ts so Facebook, LinkedIn,
WhatsApp and X re-scrape the new image instead of a cached copy.
