/* Al-Qurum Metal Industries
   Layout concept: the page is a curtain wall. Photos and content sit in glass panes
   held by brushed-aluminum mullions; one sun glint crosses the facade on load.
   White is the primary colour; navy and cobalt (from the logo) are for text and accents.
   The site is light-only on purpose: it does not switch to a dark scheme. */
