   TABLE NUMBER ALIGNMENT — append to the end of style.css

   The bug: `text-align: end` resolves against the element's own
   direction. A <th class="num"> inherits the page's RTL direction so
   "end" means LEFT, while a <td class="num ltr-text"> sets
   direction:ltr so "end" means RIGHT. Header and data therefore drift
   apart on every table in the system.

   The fix: numeric cells use PHYSICAL alignment, which means the same
   thing regardless of direction. `.ltr-text` now only controls digit
   ordering, never alignment.
