   design.txt says nothing about phones, so the calls made here are:

   * .item-tools drops onto its own line under the description. At opacity 0
     it was still holding ~180px of the item row, which is what squeezed the
     description down to one word per line on a 360px screen.
   * .row form fields stack instead of fighting over a 180px flex basis. The
     inline flex-basis values in the HTML still hold, so the narrow ones
     (type, days, icon, colour) pair up on the line below.
   * Ticks get bigger, because 26px is under the 44px touch target and this
     is the one control a magic-link visitor actually uses.
