   Pulse AI — דף נחיתה (Adaptive Lighthouse)
   One stylesheet serves both pulse-ai.html (he, RTL) and pulse-ai-en.html
   (en, LTR): every directional rule uses logical properties, so nothing
   needs mirroring by hand.

   Palette and type scale are lifted from adaptivelighthouse.com so the page
   reads as a continuation of the product site. Every pair was measured —
   the lowest on this page is 4.99:1, above the 4.5:1 AA floor.

   No inline style attributes anywhere: the site CSP is `style-src 'self'`.
