Greptile Summary

This PR introduces local serving of integration doc screenshots by rewriting raw GitHub URLs to local asset URLs via a new rewrite_integration_doc_images_in_source helper, mirroring the existing logo-serving pattern. It also fixes a markdown image-syntax typo ([!Roboflow] → ![Roboflow]) in roboflow.md and removes an unreachable HubSpot screenshot reference.

• integrations.py: Refactors _integrations_logos_url into a shared _integrations_images_url(subdir) helper; adds _integrations_doc_images_url and rewrite_integration_doc_images_in_source with a fast-path short-circuit when no raw GitHub URLs are present.
• docgen_pipeline.py: Applies the rewrite to each doc source before parsing, so the pipeline never serves images from raw GitHub.
• test_integrations.py: Four new tests verify rewriting correctness, no-op behaviour, local image existence, and the ![alt](url) syntax rule — with a fixture that guards against symlink side effects during tests.

Confidence Score: 5/5

Changes are narrowly scoped to image URL rewriting in the docs pipeline; no data paths, auth flows, or runtime state are affected.

The refactoring is a clean extraction of an existing pattern, symlink safety (unlink before re-link) is handled correctly in the shared helper, the rewrite function is a simple idempotent string replace with a fast-path guard, and four targeted tests cover the key invariants. No logic regressions were found.

No files require special attention.

Important Files Changed

Filename	Overview
packages/reflex-site-shared/src/reflex_site_shared/integrations.py	Refactors _integrations_logos_url into a shared _integrations_images_url(subdir) helper, adds _integrations_doc_images_url and rewrite_integration_doc_images_in_source to serve screenshots locally; symlink safety (unlink before re-link) is handled correctly.
docs/app/tests/test_integrations.py	New test module covers URL rewriting, no-op on non-matching sources, local image existence, and malformed [!alt](url) link syntax; autouse fixture correctly guards against symlink side effects.
docs/app/reflex_docs/docgen_pipeline.py	Adds a single rewrite_integration_doc_images_in_source call before the existing FAQ extraction step; ordering is correct and non-intrusive.
.github/workflows/docs_tests.yml	Adds packages/reflex-site-shared/** and packages/integrations-docs/** to the workflow trigger paths so doc tests run when these packages change.
packages/integrations-docs/src/integrations_docs/docs/roboflow.md	Fixes [!Roboflow](url) typo to correct  image syntax; the pipeline rewrite will serve it locally.
packages/integrations-docs/src/integrations_docs/docs/hubspot.md	Removes the malformed [!HubSpot](url) reference since hubspot.webp does not exist locally; confirmed intentional per author.
