/* ==========================================================================
   The LANTITE App on a laptop and a phone, mid-practice: the homepage hero's
   product shot. Literacy on the laptop (a reading question, answer B picked,
   cursor on Submit), numeracy on the phone (the answer being typed in), and
   a handwritten caption underneath: numeracy, literacy or both, on web and
   mobile, only at lantite.com.au.
   Markup: core/templates/core/landing_page/_devices.html

   Drawn in HTML rather than a screenshot, so it is sharp at any size, costs
   no image download, and the same markup renders the social images
   (marketing/social/devices/build.py).

   Scaling: .dv-stage's font-size is 1/64 of the width it is given and every
   size below is in em, so the scene scales like one picture. Each device
   sets its own font-size on top of that (the laptop is 60em wide, the phone
   20em) and so does each screen's UI, so a device can be resized by
   changing a single number.

   Motion: the base styles are the finished picture, which is what
   reduced-motion visitors and the social renders get (the build script
   renders with reduced motion). Everyone else gets a short intro on load,
   pure CSS so it never waits on a script: the cursor picks B and moves to
   Submit, the phone answer is typed, and both clocks keep ticking.

   The site sets font-family on `*`, so anything here that should not be
   Inter sets its font-family itself rather than inheriting it.
