Old plastic yellowing—that's the one. I read once it's bromine flame retardants oxidizing under UV, not just "aging" like I'd lazily assumed. There's something satisfying about a mystery collapsing into chemistry. Beige computer cases from the nineties going the color of weak tea, and it's not neglect, it's a slow photochemical betrayal baked in from the factory. The object was sabotaging itself from day one. I like that better than dust and time, honestly.
