Add Evolve customer story: Rest sleep coach on Langfuse

[annabellscha]

Rewrites /users/evolve from the Rest sleep-coach interview draft (not vacation rentals).

Story

Evolve (YC W18, makers of Podcast App) built Rest, a voice-and-text AI sleep coach based on the principles of CBT-I, circadian biology, and neuroscience. Every conversation is traced in Langfuse: Vapi for voice, OpenAI for text chat, plus background extractors. The team manages 100+ dynamically composed prompts (English and Spanish locale variants) in Prompt Management, reviews traces in annotation queues, and runs LLM-as-a-judge evaluators for cross-session memory.

Quotes are from Ignacio Perez (CTO) and Martín Siniawski (CEO). The /users card uses Martin's "CMS of prompts" line.

Copy (Evolve review)

• Meta: cutting the coach's memory misses in half (no 10% / 5% figures)
• Summary card 01: "based on the principles of CBT-I, circadian biology, and neuroscience"
• Error analysis: evaluators measure how consistently the coach carries context forward
• Locale variants: English and Spanish, adjusted for users in Argentina, Colombia, and Mexico
• Rest program draws on the principles of CBT-I, circadian biology, and neuroscience
• Vapi integration works out of the box
• Deep dive reframed around building cross-session memory and personalization
• What's next: datasets as a standard part of shipping

Greptile Summary

This PR adds the Evolve/Rest customer story, supporting images and customer-index wiring, while extending shared framed-image and carousel behavior with mobile zoom, links, image fitting, and keyboard accessibility.

• Adds the /users/evolve customer story and Evolve adopter entry.
• Adds logos, portraits, screenshots, diagrams, and social imagery.
• Extends Frame and carousel components with configurable zoom and linked-slide behavior.
• The new Frame keyboard handling regresses activation of existing linked images.

Confidence Score: 4/5

The PR should not merge until framed linked images retain their keyboard navigation behavior; the remaining cleanup and ordering findings are lower-impact.

The shared Frame change makes images inside existing links separately focusable and intercepts Enter/Space to open zoom, preventing keyboard users from following those links. The effect also leaves stale interactive semantics when zoom is disabled, and the customer metadata order differs from the stated placement.

Files Needing Attention: components/Frame.tsx, content/customers/meta.json

Prompt To Fix All With AI

### Issue 1
components/Frame.tsx:139-140
**Linked images lose navigation**

Every framed image is now independently focusable, including images already wrapped in links. In existing content, pressing Enter or Space on such an image is intercepted and opens the zoom modal instead of following the link. This also creates a button role nested inside an anchor. Images contained by links should be excluded from this behavior, as they are in the carousel implementation.

### Issue 2
components/Frame.tsx:156-160
**Zoom semantics remain stale**

When `zoom` changes from true to false, cleanup removes the event listeners but leaves the injected role, tab stop, ARIA label, cursor, and transition on each image. The image therefore remains exposed as an interactive zoom control even though it no longer responds. Cleanup should restore the attributes and styles added by the effect.

### Issue 3
content/customers/meta.json:13-14
**Evolve is not last**

The requested metadata order places Evolve last, but this entry is inserted before `slite`. Because this array controls customer-story sorting, Evolve will appear before Slite instead of in the requested final position.

```suggestion
    "slite",
    "evolve"
```
