From b17bd77a5c1f3653f43a394aecb890a96d25d9e5 Mon Sep 17 00:00:00 2001
From: Khokan Sardar <itzmekhokan@gmail.com>
Date: Mon, 1 Jun 2026 18:42:42 +0530
Subject: [PATCH] Docs: Fix duplicate-word and spelling typos in comments and
 docblocks.

Corrects duplicated words (such as "the the", "in in", "on on",
"is is", "from from", "and and") and a misspelling ("Compatability")
in WordPress-owned docblocks and inline comments across src/ and the
PHPUnit test suite. These are comment-only edits with no functional or
behavioral change.

Third-party and bundled libraries (ID3, PHPMailer, SimplePie, plupload,
jQuery UI, etc.) are intentionally left untouched, as they are maintained
upstream.
