*(Note: The last title appears incomplete in English. If you provide the full phrase, I can refine the translation accordingly.)*  

### Key Adaptation Choices:  
- "Picks" → **"meilleurs choix"** (implied) to sound natural in French.  
- "Fuel Your Morning" → **"Bien démarrer sa journée"** (more idiomatic than a literal translation).  
- Kept "nutritionniste" (common in French) rather than "diététicien(ne)" for broader recognition.

팟캐스트 스포트라이트: 페넬로피 트리가 빈티지 패션의 전성기와 그 화려함을 회상하다  

(또는 더 간결하게)  
팟캐스트 초점: 페넬로피 트리의 빈티지 패션 황금기 추억  

* 문화/패션 콘텐츠에 어울리는 자연스러운 번역으로, "Heyday"는 "전성기" 또는 "황금기"로 의역했으며 "Reflects on"은 상황에 따라 "회상하다" 또는 "추억"으로 표현했습니다. 제목의 가독성을 위해 약간의 단어 조정을 했습니다.
Spotlight Podcast : Penelope Tree revient sur l'âge d'or de la mode vintage et son glamour  

(Alternative option, slightly more fluid in French)  
**Coup de projecteur sur le podcast : Penelope Tree se remémore le glamour de l'âge d'or de la mode vintage**  

Notes:  
1. "Podcast Spotlight" adapts naturally to French media formats—both "Spotlight Podcast" (keeping the English term) or "Coup de projecteur sur le podcast" work, depending on the desired tone (modern vs. fully translated).  
2. "Heyday" is elegantly rendered as "âge d'or" (golden age), a common French expression for peak eras.  
3. The verb "reflects on" becomes "revient sur" or "se remémore" (reminisces) to convey nostalgia.  
4. French syntax often places adjectives after nouns ("mode vintage" vs. "vintage fashion").  

Both versions preserve the sophistication of the original while sounding natural in French. The second option adds a touch of lyrical nostalgia with "se remémore."
