robot	1b387700d3	fix(ssr): prefer index.csr.html over prerendered index.html for CSR users ... The browserIndexPath() function was resolving index.html first, which is the prerendered output with stale build-time content baked into <app-root>. Even with window.__STATION_CONFIG injection, the prerendered innerHTML still shows old content on the first paint until Angular re-renders. By preferring index.csr.html (the pure CSR shell with empty <app-root>), regular users get a clean first paint — no stale prerendered DOM to flash.	2026-08-09 01:13:50 +00:00

robot	e44f27d1cd	fix(ssr): inject fresh station config into CSR shell to eliminate flash ... The CSR shell previously rendered with hardcoded DEFAULT_CONFIG values, then the client-side API call replaced them 50-500ms later, causing a visible 'flash of stale content' (wrong colors, wrong station name). Fix: SSR server fetches live station config from the backend API before serving the CSR shell, injecting it as: - Inline <script> seeding window.__STATION_CONFIG (client reads sync) - Inline <style> setting CSS custom properties (correct colors first paint) Also adds no-cache Cache-Control headers on HTML page responses to prevent browsers from caching stale content. StationConfigService now reads window.__STATION_CONFIG on construction instead of always starting with DEFAULT_CONFIG.	2026-08-09 00:53:50 +00:00
robot	9561339cf5	fix(ssr): resolve index.html from production path for CSR shell ... The CSR shell path was hardcoded to a local dev directory (app/server/browser/index.html) which does not exist in the Docker container. Browser files are copied to /usr/share/nginx/html by the Dockerfile. browserIndexPath() now checks both production and development paths, falling back to the first that exists.	2026-08-08 20:25:29 +00:00
Hermes Robot	c5d80f4caa	feat(ssr): spider-only SSR — serve CSR shell for regular users ... Add spider detection gate to SSR server so that search engine crawlers get full server-side rendering with fresh API data, while regular users receive the static CSR app shell from disk. - backend/app/spider_detection.py: Python spider detection module - spider_detection.ts: TypeScript mirror of spider detection patterns - server.ts: SSR gate — isSpider() check before dispatching to Angular SSR engine; non-spiders get static index.html - server.spec.ts: Added spider detection unit tests - tsconfig.app.json: Include spider_detection.ts in compilation - backend/app/models.py: Fix SQLAlchemy FK resolution (user_models import)	2026-08-08 17:48:37 +00:00
