A pricing page, as an example

How this page works

The table above is an island: static HTML that a small module enhances once it scrolls into view. Without JavaScript you get the complete monthly table — which is also what a crawler indexes and what prints. The billing-period control is created by the module, so the page never shows a control that cannot work.

The table sits in its own horizontal scroll container, focusable from the keyboard, so the columns stay reachable at 320px without the page itself scrolling sideways.

What the figures mean

Nothing. They are placeholders sized to look plausible in a layout. Replace them with your own before deploying, along with the plan names.
