/* ============================================================================
   IRONCLAD — Roller Door
   Palette drawn from the Australian building site, not a colour wheel:
   galvanised/zincalume steel, oxidised iron, red earth and true AS/NZS
   hi-vis fluoro — the acid yellow-green off a vest, not a generic warning
   amber. Corrugated-iron ridging (the literal "ironclad") shows up as a
   texture, not just a name. Sections are colour-blocked plates offset at an
   angle, like lapped sheets of roofing. The site opens through a roller
   door — the one deliberate entrance moment — before the page underneath.
