Create separate CSS bundles to reduce shop page load times:
- app-shop.css (45KB/7.8KB gzip): Shop pages only, no daisyUI
- app.css (139KB): Admin pages with daisyUI and theme editor
Key changes:
- Add app-shop.css with targeted @source paths for shop files only
- Move .preview-frame rules from theme-layer2-attributes.css to app.css
- Delete fonts.css (fonts now generated inline by CSSGenerator)
- Add inline all-fonts generation in theme editor for typography switching
- Configure separate Tailwind profiles and watchers for both bundles
Shop pages now load 54% less CSS by excluding:
- daisyUI components (admin only)
- .preview-frame theme switching rules (editor only)
- Admin-specific Tailwind utilities

Add path_resolver parameter to font generation functions so both
font preloads and CSS @font-face declarations use the same digested
paths in production. This prevents duplicate font downloads when
preloads were using digested paths but CSS used non-digested paths.
- Add path_resolver parameter to Fonts.generate_font_faces/2,
Fonts.preload_links/2, and Fonts.generate_all_font_faces/1
- Update CSSGenerator.generate/2 to accept path_resolver
- Update CSSCache.warm/0 to use Endpoint.static_path/1
- Move CSSCache to start after Endpoint in supervision tree
- Add 1-year cache headers for static assets

Create a DRY Fonts module that centralizes all font definitions and
generates @font-face declarations dynamically based on typography preset.
- Add Fonts module with typography font mappings
- Generate @font-face CSS in CSSGenerator based on active preset
- Add font preload links in shop_root layout for performance
- Remove hardcoded font-face declarations from CSS
This improves font loading performance by only loading fonts for the
active typography preset and preloading critical fonts.

The shop.html.heex and shop_root.html.heex were both full HTML documents.
When nested (root layout + live layout), this created invalid HTML with
duplicate <!DOCTYPE>, <html>, <head>, and <body> tags.
This caused:
- "Cannot bind multiple views to the same DOM element" console errors
- Failed Lighthouse audits
- Potential rendering issues
Fix:
- shop_root.html.heex: Now contains the full HTML document with theme
settings, CSS variables, and data attributes
- shop.html.heex: Now just passes through @inner_content
Results:
- Console errors: Gone
- Best Practices: 96 → 100
- Total Blocking Time: 140ms → 30ms
- HTML validation: Passes

Self-hosted fonts:
- Download all 10 typefaces (35 font files, 728KB) from Google Fonts
- Create @font-face declarations in assets/css/fonts.css
- Remove Google Fonts external dependency from layouts
- Privacy improvement (no Google tracking)
- Performance improvement (no DNS lookup to fonts.googleapis.com)
- GDPR compliant (no third-party requests)
Admin access:
- Add /admin route that redirects to /admin/theme (requires auth)
- Remove Admin link from footer (too visible for visitors)
- Shop owners can bookmark or type /admin directly
Layout improvements:
- Create shop_root.html.heex as minimal root for shop pages
- Shop pages no longer show admin nav bar
Other:
- Update .gitignore to exclude digested static files
- Add PageSpeed 100% task to ROADMAP.md
- Fix test to check /users/settings instead of shop homepage

- Add .themed class as shared selector for both shop and preview
- Move visual/behavioral styles from .preview-frame to .themed
- Keep .preview-frame only for CSS variable switching (editor live preview)
- Update CSSGenerator to target .themed instead of .shop-root
- Refactor CSS files to use native CSS nesting syntax
- Update tests to reflect new class structure
This improves maintainability by:
- Eliminating duplicate selectors (.shop-root + .preview-frame)
- Using modern CSS nesting (94%+ browser support)
- Clear separation: .preview-frame = vars, .themed = styles

- Fix asset paths in shop layout (css/app.css, js/app.js)
- Add Google Fonts preconnect and stylesheet link
- Update theme-layer2-attributes.css to target both .preview-frame
and .shop-root so theme styles apply to real shop pages
- Properly duplicate attribute selectors (e.g., [data-mood="warm"])
for both .preview-frame and .shop-root

- Create LoadTheme plug for loading theme settings
- Add shop layout with inline CSS injection (~400 bytes vs 17KB full)
- Create ShopLive.Home at / using shared ShopComponents
- Wire up CSS cache invalidation when theme settings change
- Replace Phoenix welcome page with themed shop home page
The shop layout injects only the active theme CSS variables inline,
achieving a 97% reduction compared to the full variants file used
by the theme editor.

- Add Google Fonts link to root layout for typography presets
- Add data-mood, data-typography, data-shape, data-density attributes to preview-frame
- Create theme-layer2-attributes.css with attribute-based CSS from demo
- Move theme CSS files from priv/static/css to assets/css for proper compilation
- Update CSS import order (primitives → layer2 → semantic)
- Add 'css' to static_paths to serve theme CSS files
This fixes the issue where theme controls updated the database but didn't
visually affect the preview. The demo's attribute-based CSS system is now
properly integrated with the Phoenix LiveView implementation.
