CURCY WooCommerce Session increases first-visit latency and cache misses

We use CURCY Premium 2.4.2 with WooCommerce, TranslatePress Business and LiteSpeed/Hostinger caching.

Clean anonymous first requests are typically x-litespeed-cache: miss with approximately 2.6–3.4 seconds TTFB. These requests set CURCY currency cookies and a WooCommerce session cookie before the visitor has interacted with the cart. Repeated requests in the same anonymous session then become cache hits at approximately 0.02–0.03 seconds.

CURCY was configured with WooCommerce Session storage, Cache Compatible disabled and Switch by JavaScript enabled. TranslatePress language paths determine SEK, EUR, DKK and PLN.

We are not claiming that CURCY is the site’s only performance issue, but its anonymous session and cookie handling appears to contribute materially to the first-visit cache miss.

What is the recommended supported configuration for this stack? Can we use Cookie storage or Cache Compatible mode without risking wrong currencies in visible prices, JSON-LD, cart or checkout? Does TranslatePress Auto Detect require WooCommerce Session storage? Are there recommended LiteSpeed cache-vary settings or known performance fixes for CURCY 2.4.2?
