▶ General formulas (reference)
Token conversion (English):
  1 token ≈ 4 characters ≈ 0.75 words
  1,000 words ≈ 1,333 tokens
Scope conversion to monthly:
  if scope = day → monthly_tokens = tokens × 30
  if scope = month → monthly_tokens = tokens
  if scope = year → monthly_tokens = tokens ÷ 12
Cost formula:
  input_tokens = monthly_tokens × split_ratio
  output_tokens = monthly_tokens × (1 − split_ratio)
  monthly_USD = (input_tokens ÷ 1M) × in_rate + (output_tokens ÷ 1M) × out_rate
  monthly_MYR = monthly_USD × USD_to_MYR_rate
