headers: 1150 → 289 (-75%); removed pecl_http C constants, CGI env vars,
HTTP status reason phrases, PHP superglobals, Apache module names, WAP-era
device cruft, defunct platforms (BAE/FirePHP/Tomboy/Mosso/Prototype.js/
Hixie-76 WebSocket/RFC2965 Cookie2), per-app webhook signatures and CSRF
headers, and joke/typo/fragment entries.

parameters: 6514 → 5224 (-20%); removed case-insensitive duplicates,
numbered single-app dump residue (u1-u50, sql* series), pfSense WebGUI
form fields, SMF install fields, phpMyAdmin admin-form fields, phpBB
forum-specific entries, ID3 audio-tag tool entries, all 1- and 2-letter
entries, and 3-letter entries that aren't well-known abbreviations.
