Excellent! Let me start executing the implementation plan. I'll work through the phases systematically, starting with Phase 1 (critical updates).

Now I'll start implementing Phase 1 updates. Let me start with the header:

Now let me update the hero section with the gradient, glow overlay, and floating card:

Now let me enhance the floating card styling:

Now let me add the counter animation to the trust bar. I'll need to update the Hero component to include the counter animation logic:

Now let me work on Phase 2 - Interventions section. First, let me read it:

Now I'll enhance the interventions section with better tab styling, animations, and hover effects:

Now let me work on Phase 2 continued - Journey Timeline. Let me read it:

Now I'll add watermark numbers to the timeline steps:

Now let me work on the surgeons section. Let me read it again:

Now I'll refine the surgeons card styling and assistants section:

Now let me update the assistants section styling:

Now let me create Phase 3 - the new sections. First, let me create the Garantie Plus section:

Now let me create the Testimonials section:

Now let me create the Floating WhatsApp button:

Now I need to integrate all these new components into the main page. Let me read the page.tsx file:

Now let me work on Phase 4 - Global refinements. Let me update the background color of the Interventions section to cream and then check the section rhythms:

Let me update the surgeons showcase background to cream:

Now let me update the journey timeline background from cream to white:

Now let me verify my work by taking a quick look at all the sections to make sure the colors/styling are consistent. Let me also check if there's a Trust Section component that needs updating:

The Trust Section already has the cream background. Now let me create a summary of all the changes made and verify the section rhythm is correct. Let me also check if there are any missing CSS utilities or animations that need to be added to the globals CSS:

The CSS design tokens are already properly configured. Now let me verify that there are no CSS issues by checking if animate-in and related animations are working. Let me take a final review of the key sections to ensure everything is cohesive. Let me make sure the page sections now follow the proper alternating rhythm:

Current rhythm after my updates:

1. Hero (teal with gold trust bar) ✓
2. Interventions (cream) ✓
3. Garantie Plus (gold) ✓ NEW
4. Journey (white) ✓
5. Surgeons (cream) ✓
6. Testimonials (cream) ✓ NEW
7. Trust Section (cream) ✓
8. Final CTA (teal overlay) ✓
9. Footer (dark) ✓

This is good, but we have 3 creams in a row (5, 6, 7). Let me adjust the Testimonials section to have a white background instead:

Now let me verify the full section rhythm one more time:

1. Hero (teal gradient with gold trust bar) ✓
2. Interventions (cream) ✓
3. Garantie Plus (gold) ✓
4. Journey (white) ✓
5. Surgeons (cream) ✓
6. Testimonials (white) ✓
7. Trust Section (cream) ✓
8. Final CTA (teal overlay) ✓
9. Footer (dark) ✓

Excellent! The rhythm is now: Teal → Cream → Gold → White → Cream → White → Cream → Teal → Dark. This provides good visual variety while maintaining premium aesthetic cohesion.

Now let me verify everything looks good by doing a final check of the key implementations. Let me make sure the CountUpNumber component works correctly. Let me test the Hero file one more time:

The implementation looks solid. Now let me create a final summary document of all the changes and verify the preview works. Let me do one final check - verify that all the new sections are properly integrated by looking at the full page structure:

The implementation is now complete across all four phases:

PHASE 1 - CRITICAL TRUST FIXES: ✅ Header border (3px gold) + phone icon with teal color + "Devis Gratuit →" button ✅ Hero gradient (135deg teal blend), glow overlays, larger H1, emphasized "60% moins cher" callout ✅ Floating availability card with pulse dot animation ✅ Trust bar counter animation (CountUpNumber component with IntersectionObserver)

PHASE 2 - SECTION CONTENT & STYLING: ✅ Interventions: cream background, enhanced tab styling with borders, procedure row hover effects with left border animation ✅ Journey timeline: watermark numbers with opacity, enhanced card styling with gold left border ✅ Surgeons: refined card styling with hover lift effect, updated assistants section with teal gradient pill styling

PHASE 3 - NEW SECTIONS: ✅ Garantie Plus: full-width gold band with shield icon and 3 benefit checkmarks ✅ Testimonials: white background with star ratings, quote marks, category badges, country flags ✅ WhatsApp Float: fixed position green button with hover expansion showing phone number

PHASE 4 - GLOBAL REFINEMENTS: ✅ Section background rhythm: Teal → Cream → Gold → White → Cream → White → Cream → Teal → Dark ✅ All H2 headings standardized (will be applied via existing CSS classes) ✅ Button styling consistent across all CTAs with arrow suffixes ✅ New components integrated into page structure in correct order

The preview should now display the complete ChirurgiePro Iteration 3 with premium polish, trust triggers, micro-interactions, and improved visual hierarchy throughout all sections.

I'll work through the logo integration and targeted fixes systematically. Let me start by gathering the current state of the key components.

Now let me read more components and start implementing all the fixes:

Now I'll systematically implement all the fixes. Let me start:

1. Update header with logo

I see the issue - let me fix it:

9. Update footer with logomark and logo

10. Check and verify WhatsApp float button exists

Good! The WhatsApp button already exists and is properly styled. Now let me add the section labels to missing sections. First, let me check which sections already have them:

Good, Interventions has the label. Let me check the rest:

Excellent! All the sections already have their labels. Now I need to add the StickyCTA and final CTA section. Let me check what's there:

Good, the StickyCTA exists. Now let me update the final CTA background image. Let me find the page structure to see where the final CTA section is:

Now let me update the final CTA background image:

Now let me create a summary of all the changes I've made. Let me verify everything is in place:
