The three CTAs (hero, mid-page, §7) were <a class="btn-buy"> that only worked
through JavaScript. They are now native <form method="post" target="_blank">
elements posting basket=[{"product_id":12,"qty":1}] + clear=1 to
https://20.odoo4projects.com/shop/post_basket, so the buy works with JavaScript
disabled; the button keeps the brass styling and the same size classes.
static/buy.js no longer builds a form on click. It is now pure progressive
enhancement: a capture-phase submit listener appends the utm_source/medium/
campaign hidden inputs from the cookies and lets the native submit proceed.
One page-scoped declaration keeps the button height at 55px: a <button> takes
line-height:normal from the UA font shorthand where the <a>s inherited the body
line-height (measured 49.19px vs 54.78px without it).
The three Reserve-your-seat CTAs posted to /support.html#contact. They now
run the same checkout path as the main page's Buy Now: a new page-local
static/buy.js mirrors script.js buyNow() (POST basket to
20.odoo4projects.com/shop/post_basket, clear=1, UTM cookies appended) and
binds .btn-buy via one delegated click handler. CTAs become
.btn-buy[data-id=12]; label unchanged. script.js and the homepage untouched.
The Price-and-booking section keeps a second, smaller link to
/support.html#contact so readers who have questions still have a fallback.
