/* AIWON AAC Blocks · Brickcem Conmate Pvt. Ltd.
   Layout: AAC-grey paper pages on a left-aligned 12-column grid with generous air; the site opens on one full-bleed
   water scene (an AIWON block floating, because it is lighter than water); dark graphite bands carry the plant; tools
   sit on raised paper panels. The 3 mm AIWON Bond joint (jade) is the only rule the site draws. */
