From 3aff388bc4e8d64583d144f3be9c0aff9a54f14d Mon Sep 17 00:00:00 2001 From: Rito Rhymes Date: Mon, 23 Mar 2026 11:33:42 -0400 Subject: [PATCH] docs: contain horizontal overflow in C API descriptions Some documentation pages contain long C API signatures that can exceed the content width and cause page-wide horizontal scroll overflow. Apply contained horizontal scrolling to C API description blocks and keep their signature rows on one line. This preserves signature formatting while preventing them from breaking page layout. Contained horizontal scrolling is preferred over wrapping here because code fidelity is the priority. These blocks are intended to remain representative of the code itself. Wrapping distorts spacing and line structure, which affects fidelity, creates misleading renderings, and reduces readability.
