When the Telegram first name yields no usable letters, fall back to the @username taken whole (trimmed + length-capped, never character-stripped like the real name) rather than a sanitized form; the generated placeholder is reached only when no username is set. Precedence: real name -> @username (verbatim) -> placeholder.
