/* ========================================================================
   pitch-deck.css — page-unique styles for the RetirePlusPlus $30M Series B
   meeting deck.

   Phase-1 page CSS (owner: P2 pitch-deck). Consumes the §1 SEMANTIC tokens
   from vc-tokens.css and the shared components in vc-components.css /
   vc-b2b2c.css / vc-charts.css / vc-utilities.css. There are NO :root palette
   blocks and NO [data-theme] override blocks here — those live ONCE in
   vc-tokens.css (vc-aliases.css preserves any legacy --vc-*/--rpp-* names so
   nothing breaks). NO raw hex values.

   CSP (MASTER BUILD SPEC §4, FIX F11): this file owns ALL pitch-deck slide +
   chrome styling that pitch-deck-nav.js previously injected via a runtime
   <style> element (.pitch-slide, the slideIn keyframe, .pd-counter, .pd-nav,
   .pd-nav-btn, .pd-progress*). The JS now only toggles classes/text and sets
   the one sanctioned dynamic style (the progress-bar `--progress` width var,
   consumed below).
