/* ============================================================
   optimization.css — Mastery Logistics Systems
   Optimization page-specific styles.
   Global styles live in style.css.
   Desktop styles first. Mobile overrides at the bottom.

   COMPONENT REUSE:
   - .banner — slim warm band component introduced on Visibility
     & Tracking.
   - .feature / .feature--reverse — standard alternating two-column
     feature block on white.
   - .cta-banner — standard closing CTA.

   NEW COMPONENTS INTRODUCED HERE:
   - .optimatch — driver-match score visual for OptiMatch feature.
   - .cards2 / .cards2__card — 2-card warm block.
   - .aic — AI Capacity Entry card visual (text → AI → trucks).
   - .tours — Tours card visual (day-labeled route legs).
   - .aic-stat — AI Capacity Entry stat block (two horizontal stats).
   - .leo — Leo callout strip (chat visual comes from shared /leo.css).
   - .labs-bridge — Mastery Labs dark chapter break.
   - .feature-dark — now in shared /feature-dark.css, since the
     Shippers page carries the OptiRoute block too.
   - .cards4-dark — 4-card grid on dark background.
   - .fuel-vis / .tetris-vis / .eta-vis / .cons-vis — distinct card
     visuals for each Mastery Labs model.

   PAGE STRUCTURE:
   1. Hero (dark, two-column)
   2. Slim banner (light warm)
   3. OptiMatch feature (white, in-app flagship)
   4. 2-card block (light warm, AI Capacity Entry + Tours)
   5. AI Capacity Entry stat block (white, proof moment)
   6. Leo callout strip (light warm)
   7. Mastery Labs bridge (dark, chapter break)
   8. OptiRoute feature (dark, Labs flagship)
   9. 4-card Mastery Labs block (dark, more Labs models)
   10. CTA banner (dark)

   NOTE: Sections 7–10 are intentionally all on dark backgrounds
   to visually separate the Mastery Labs experience from the
   in-app optimization above.
