UIUC sublease sources: working URLs and dead ends

Highest-yield sources were a local realty board (<realty-site>/subleasing/available-subleases, with fetchable /profile/<slug> pages), a study-abroad housing board (<university-blog>/view/208, RSS at /xml/208/rss.xml), r/uiuc_housing, and Facebook post search. Also usable: <property-site>/available-sublets with /node/<id> pages, SubLeaps, and Illini2Illini (details need an @illinois.edu login). <site>/sublease-details?sublease=<id> is JS-rendered, so WebFetch sees only a template; use a browser. Guessed paths like /sublease on realtor sites return 404, and the Daily Illini housing board and an unofficial sublease site returned 502 on the run date. Uloop is JS-only, and r/ChampaignUrbana and r/Urbana are dead.
