/* ============================================================
   BAYOCORP LINKS - the digital reception page
   ------------------------------------------------------------
   Palette and type are the company's own, not this page's:
   black #000000, brand gold #FFDE59, white, warm light grey for
   secondary text - the three colours in the logo file itself
   (assets/logos/favicon.svg) - and the Poppins / Inter pairing
   www.bayocorp.uk loads on every page.

   Radii come from the site's tokens rather than being invented
   here: 12px on anything card-shaped, 6px on anything button- or
   chip-shaped. Nothing on a Bayocorp surface has a square corner.

   Gold NEVER carries body text. It is a fill (gold panel, black
   text, ~15:1) or an accent on black. On a light ground it sits
   near 1.4:1 and is unreadable.

   Mobile first throughout: most visitors arrive from Instagram on
   a phone. Every interactive element clears 44px, body text never
   drops below 16px, and the layout is verified at 320/375/390/430.
