   Rules in this block do exactly one thing: turn an attribute into a

   why nothing here can win a fight it should lose — the responsive caps
   further up still cap, .img-fig.bare still strips its frame, and a page
   that uses none of the controls renders byte for byte as it did.

   The ladders are deliberately closed sets rather than free numbers. A
   free value would have to travel from the editor into a style attribute,
   which is the one hole the theme editor already refuses to open, and the
   design system has no use for a 437px figure. */

/* ============================ FORM ANTI-SPAM ============================
   The honeypot field. Deliberately NOT `display:none` and NOT
   `visibility:hidden`: those are the two properties a form-spam bot checks
   before deciding whether to fill a field in.

   The obvious alternative — position:absolute;left:-9999px — is worse than
   it looks. Its containing block here is the page, so it pushed the
   document 9,945 pixels wide and every page carrying this form gained a
   horizontal scrollbar. viewcheck.py caught it; nothing about the rendered
   page looked wrong.

   The clip-path pattern below is the standard visually-hidden recipe: a
   1×1 box that is clipped away, so it occupies no layout and creates no
   overflow. It stays in the accessibility tree, which is what aria-hidden
   and tabindex="-1" on the wrapper are for — the honest way to hide
   something from people while leaving it visible to a machine that only
   reads markup. */
