Tiers drive physical traits and serial checks; guide item

Fans (1/2/3/3) and power connectors (6/8/8/8+8) follow the real chip's tier, so a fake shows its real tier physically. Serial numbers (brand prefix, tier code, factory code, four digits) are drawn on the sticker from card state; the label bar gets power-and-fans and serial rows, eight in total, with a framed panel. A graphics card appraisal guide item holds the rules. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Labels: eight rows (model, build, fan blades, contacts, bracket, print, serial, seal); serial text rules by brand and tier
