YoY shift: Unscored

Year-over-year tone shift - average net-tone change across Risk Factors and MD&A vs the prior 10-K.

Why YoY instead of absolute: the LM lexicon has ~6.6× more negative words than positive (legal/risk-disclosure language is heavy on hedging), so every 10-K reads bearish on raw tone. Year-over-year change strips that bias and surfaces the actual shift in management's framing.
