/**
 * Account routes — profile, password, avatar.
 *
 * Sections:
 *   GET  /                  -> render full account page (profile + password + avatar + danger)
 *   POST /profile           -> update bio
 *   POST /password          -> change password (verify current, hash new)
 *   POST /avatar            -> upload avatar image (multer)
 *   POST /avatar/remove     -> clear avatar_url
 *
 * Each form has its own POST handler. After success, redirects back to
 * /account?success=... so the page picks it up via query string.
