Change: Added one sentence: "Currency and special character discipline: when the desired rendered text contains '$', '%', '#', or similar characters, write the prompt character literally (e.g. '$0 Down') rather than spelling it out in words ('dollar zero down') -- image models render the literal character correctly when given it directly; word-spelled versions produce unintended literal transcriptions."
Effect: v1 headline said "DOLLAR ZERO DOWN" because the prompt spelled it out. v2 corrected to "$0 Down" by passing the literal character.
