/* SecondFactor.ai — neutral surface layer.
   Loaded LAST on every page (after chrome.css). Turns everything below the hero into a
   white canvas: sections start with a hairline and a faint neutral wash instead of a blue
   gradient, cards are white with a neutral border and soft shadow, alternate bands use a
   cool-grey tint. Only the home hero (.hero) keeps its gradient art; inner-page intros
   (.hero-in) become plain, left-aligned white headers.
   The page CSS layers (home inline styles, motion.css) already stack !important overrides with
   long selectors, so rules here use !important plus `html body` and, where needed, a `:not(#sf)`
   specificity bump (no element has id="sf"; it just adds id-level weight). */
