Two pointed bugs on the article detail page:
1) Width alignment. The right-rail Related Articles and Related Forum
Posts boxes were free-stretching to the lg:col-span-4 width while the
SidebarAdStack below them rendered ads at their natural 300px (items-
end, right-aligned). The visual result: boxes overhung the ad column
on both edges. Wrapped each sidebar in an inner `w-full lg:w-[300px]
lg:ml-auto` div so every block (ads + boxes + newsletter) shares one
300px column on lg+ and stays full-width on mobile. Applied to both
article templates (/articles/[slug] and /news/[slug]).
2) Placeholder rendered the old "AV BEAT" wordmark when an article had no
featured image. Rebuilt article-placeholder.svg around the new brand
mark — the A-monogram tile with the blue gradient (#2563EB→#1E3A8A)
that matches AnimatedLogo + the rest of the brand-gradient system.
Same 1200×630 dimensions so OG/feed embeds aren't affected.
