/* =========================================================
   FLAMOURIA TECH — Portfolio
   Design concept: engineering-schematic / blueprint language.
   Grounded in the subject: the person behind this site reads
   rack diagrams, network topologies, and monitoring dashboards
   for a living (and a hobby). The hero diagram mirrors his
   actual home-lab pipeline. Certifications get a timeline
   because they are a real, dated sequence. Projects get
   "LOG" labels because that's how a sysadmin actually refers
   to a piece of completed work.
