/**
 * PHP mirror of assets/src/builder/logic/dataSources/builtins.js — same
 * camelCase key names in `$context['extra']` as the JS side
 * (`urlParams`/`currentUser`/`userRoles`/`postMeta`/`userMeta`/
 * `cookies`), not PHP-conventional snake_case. This was a real,
 * previously-inert bug: an earlier version of this file read
 * `url_params`/`current_user`/`user_roles`/`post_meta`/`user_meta`
 * (snake_case) while every populator of `extra` — this class's own JS
 * mirror, and Includes\Logic\Context_Builder — always wrote camelCase.
 * The mismatch went unnoticed because nothing populated `extra` at all
 * until Context_Builder existed, so every one of these sources silently
 * resolved to nothing regardless of which case convention "won." Found
 * by actually wiring real data through and testing end-to-end, not by
 * inspection — a reminder that a mirrored-but-never-exercised code path
 * can drift silently. Keys must match `Context_Builder::build_extra()`'s
 * output exactly, always.
