   and 'Agentic Cloud Delivery Platform — The Developer Experience'
2. Footer: 'Confidential · For Senior Leadership' → 'Internal'
3. Title slide subtitle: removed 'Senior Leadership Briefing' (clean title)
4. S&P Global brand theme (colors extracted from live spglobal.com CSS):
   - H1/H2: #D6002A (S&P red-core, confirmed from logo SVG + compiled CSS)
   - Title slide bg: #1B1B1B (S&P grey-90) with 8px #D6002A top accent bar
   - Body text: #1B1B1B (grey-90)
   - Blockquote border: #D6002A, text: #2E2E2E (grey-80)
   - Table headers: #F0F0F0 (grey-5)
   - Font: 'Akkurat Pro' (S&P corporate typeface) with web-safe fallbacks
   - theme: default kept as Marp base (simple)
