0fba2d567c feat: add .btn to critical-bootstrap.css for navbar CTA 
Bootstrap .btn class used above-the-fold in navbar needs to be
in critical CSS to prevent CLS when Bootstrap is deferred.

9afdd6ee1d perf: defer style.css - eliminate last render-blocking CSS 
- Add site structure, accessibility, typography to critical-bootstrap.css
- Defer roi-main-style (style.css) with media='print'
- Goal: 0 blocking CSS files (was 1 file, 19KB)

b4071bf598 perf: Defer fonts.css and variables.css, inline critical CSS 
- Add @font-face declarations to critical-bootstrap.css inline
- Add critical CSS variables (colors, fonts) inline
- Defer fonts.css (utilities only, @font-face inline)
- Defer variables.css (critical vars inline)

Now only style.css is render-blocking (~19KB)
All other CSS deferred with media=print + onload

62a0f17b21 perf: Defer Bootstrap with inline critical CSS for LCP optimization 
- Add grid system (row, col-*) to critical-bootstrap.css to prevent CLS
- Add text utilities, sizing, spacing, and alert component to critical CSS
- Enable CriticalBootstrapService to inline critical Bootstrap in <head>
- Defer bootstrap-subset.min.css (21KB) via media=print + onload
- Fix preload pointing to wrong Bootstrap file (was 227KB, now 147KB)

Expected improvement: ~970ms reduction in render-blocking CSS

d5a2fd2702 perf: defer Bootstrap CSS with critical subset inline 
- Created Assets/css/critical-bootstrap.css (~10KB subset)
  Contains only Bootstrap classes used in above-the-fold components:
  container, navbar, flexbox, dropdown, spacing utilities

- Created CriticalBootstrapService (singleton)
  Injects minified critical Bootstrap in <head> at priority 0
  Output: <style id="roi-critical-bootstrap">...</style>

- Modified enqueue-scripts.php
  Bootstrap now loads with media="print" + onload="this.media='all'"
  Full 31KB Bootstrap loads async, doesn't block rendering

- Updated CriticalCSSHooksRegistrar
  Now registers both CriticalBootstrapService (priority 0)
  and CriticalCSSService (priority 1)

Flow:
1. wp_head (priority 0) → Critical Bootstrap (~10KB inline)
2. wp_head (priority 1) → Critical Component CSS (~4KB inline)
3. Bootstrap full (31KB) loads deferred, non-blocking

Expected PageSpeed improvement: ~400-600ms LCP reduction
