Merge pull request 'fix(ssr): remove color defaults from :root in _themes.scss' (#12) from fix/remove-root-color-defaults into main

The server-injected inline <style> was missing the three derived gradient
variables (--sky-gradient, --sunset-gradient, --mixed-gradient) that
components reference via var(). Without them, components fell back to
SCSS build-time defaults on the first paint, causing a visible flash
before ThemeService.apply() corrected the values.

Additionally, migrate three component SCSS files from hardcoded SCSS
color variables to CSS custom properties so the first paint uses the
server-injected runtime colors:
- login.component.scss: backgrounds, text colors, borders, focus rings
- events.component.scss: event date card background gradient
- about.component.scss: donation CTA background gradient

+# Prerendering & SSR Build Guide
+
+## Overview
+
+The KMountain Flower Radio application uses Angular SSR with prerendering (SSG — Static Site Generation) for its five public-facing routes. Prerendered routes are compiled to static HTML during `ng build` and served directly from disk at runtime.
+
+## Public Routes
+
+All routes listed in `prerender-routes.txt`:
+
+| Route       | Build Output                                      |
+|-------------|---------------------------------------------------|
+| `/`         | `dist/radio-station/browser/index.html`           |
+| `/about`    | `dist/radio-station/browser/about/index.html`     |
+| `/schedule` | `dist/radio-station/browser/schedule/index.html`  |
+| `/events`   | `dist/radio-station/browser/events/index.html`    |
+| `/contact`  | `dist/radio-station/browser/contact/index.html`   |
+
+## Configuration Files
+
+| File                        | Purpose                                                      |
+|-----------------------------|--------------------------------------------------------------|
+| `angular.json`              | Prerender + SSR config (`prerender.routesFile`, `ssr.entry`) |
+| `prerender-routes.txt`      | One route per line — the list of routes to prerender         |
+| `server.ts`                 | Node SSR entry point + `PRERENDERED_ROUTES` constant         |
+| `src/app/app.server.routes.ts` | Server-side route definitions                               |
+
+## Build Scripts
+
+### `npm run build` / `npm run build:ssr` / `npm run build:prerender`
+
+```bash
+npm run build:ssr
+# or equivalently
+npm run build:prerender
+# or
+ng build
+```
+
+All three scripts execute `ng build` (default configuration: `production`). Because `angular.json` has both `prerender` and `ssr` configured, a single `ng build` produces:
+
+1. **Browser bundle** — client-side JavaScript + CSS under `dist/radio-station/browser/`
+2. **Server bundle** — `server.mjs` + `main.server.mjs` under `dist/radio-station/server/`
+3. **Prerendered HTML** — static HTML files for each route in `prerender-routes.txt`
+
+### `npm run serve:ssr:radio-station`
+
+```bash
+node dist/radio-station/server.mjs
+```
+
+Starts the Node SSR server on port 4200. Prerendered routes are served as static HTML; all other routes fall back to SSR or a 404 handler.
+
+## Adding a New Prerendered Route
+
+1. Add the route path (one per line) to `prerender-routes.txt`
+2. Add the route to `PRERENDERED_ROUTES` in `server.ts`
+3. Rebuild: `npm run build:ssr`
+
+## Build Output Structure
