Subject: [PATCH] fix(article): fix Opus article body font size too small
 (#1897)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

New Opus format uses font_level string instead of numeric font_size,
causing font size to fall back to Flutter theme default (14px) instead
of the expected 16px. Added Word.effectiveFontSize: small→13px,
others→16px (consistent with legacy HTML article format).
