Reporting for duty.
18 days later, things have much improved. Primary's been nearing completion, and since 4 days, I've been slowly bringing her down from 75 F to 40 with 5 degree decrements.
Beer dropped bright clear now, and the sulphur's gone. In its place came honey notes, as well as toasty biscuity flavours. The honey hints of sweetness which is actually not really there (1.050 to 1.006) and the 25-ish IBUs give a nice complementary bitterness. El Dorado turned slightly marzipany-almondy.
Goes to show you can't hurry beer, and a beer one week into primary is nothing like its eventual mature form.
Now: secondary for a couple weeks and then, into the bottle. Bee keeper's getting restless for her beers.
