perf(marketing): client-side render below-the-fold homepage sections

[TorstenDittmann]

Summary

• Client-side renders all homepage sections below LogoList (Bento, Pullquote, Ai, CaseStudies, Features, Map, Scale, Pricing) to eliminate ~580ms of SSR CPU time per request.
• Adds a single 100vh SSR placeholder to keep the footer below the fold on initial paint.
• Keeps Hero, Platforms, LogoList, FooterNav, and MainFooter SSR'd for fast first paint and SEO coverage.
• Removes an unused browser import from logo-list.svelte.

Expected impact

Metric	Before	After
SSR time (warm)	~585 ms	~5 ms
Speedup	—	~100×

Notes

• prerender = false is intentionally preserved so Statsig hero experiments continue to be evaluated server-side.
• This is a band-aid fix; the long-term solution is prerendering with client-side experiment assignment and designed skeleton states.

Greptile Summary

This PR defers eight below-the-fold homepage sections to client-side rendering via {#if browser}, replacing them with a 100vh placeholder during SSR. The stated ~100× SSR speedup is credible and the implementation is straightforward. The one follow-up worth considering is switching to dynamic import() for the deferred components so their module code is also split out of the initial JS bundle.

Confidence Score: 5/5

Safe to merge — no correctness, security, or data issues introduced.

Changes are minimal and intentional: a standard {#if browser} CSR gate and removal of an unused import. No P0 or P1 findings; only a P2 bundle-size suggestion.

No files require special attention.

Important Files Changed

Filename	Overview
src/routes/(marketing)/+page.svelte	Wraps below-the-fold sections in {#if browser} for CSR-only rendering with an h-screen SSR placeholder; logic is correct and intentional.
src/routes/(marketing)/(components)/logo-list.svelte	Removes an unused browser import — clean housekeeping, no logic changes.

@greptile-apps Noted on the SEO concern, but this is an intentional trade-off for this specific page. The marketing homepage relies on server-side Statsig experiment evaluation for the hero section, which requires prerender = false. The SEO-critical content (hero copy, platform descriptions, footer links) remains SSR'd. The below-the-fold sections (features, pricing, etc.) are not primary landing traffic drivers — users land on dedicated /products/* and /pricing pages for that content. This is documented as a band-aid fix until we can prerender with client-side experiment assignment.
