 * Right-to-left corrections, loaded on top of theme.css (not instead of it).
 *
 * theme.css is written in logical properties — margin-inline-start,
 * inset-inline-end, text-align: start — so nearly all of the layout mirrors
 * itself with no help. This file exists only for the handful of things CSS
 * logical properties cannot express: physical transforms, an animation whose
 * direction is baked into a percentage, and a glyph that points one way.
 *
 * Keep it this small. Anything that can be fixed with a logical property in
 * theme.css belongs there instead — a rule in this file is a rule that has to
 * be kept in step with its left-to-right twin forever.

 * The labels are placed on the same 760x720 coordinate grid the SVG draws in.
 * Logical properties would mirror the labels while leaving the SVG geometry
 * where it is, putting Being's name on Becoming's corner. Mirroring both
 * would be worse still: the model's vertices are a published figure, and a
 * reader following the book alongside the site would find its corners swapped.
 *
 * The text inside each label still runs right to left, which is the part that
