2026 visual refresh
-------------------
- Automatically use a standard block header when Header Banner is enabled,
  removing the extra right-side flex gap. Preserve banner centring, configured
  sizes, mobile images and search positions; constrain oversized mobile rules.
- Fixed Header Banner extension overflow by allowing its wrapper to shrink
  within the header while preserving image proportions and search positions.
- Slightly darkened the warm header gradient and improved heading contrast
  in confirmation dialogs, including the Delete cookies dialog.
- Centred forum-count badges on both axes and changed pink to blood-red/amber.
- Skinned native file-upload buttons, select arrows, checkboxes and radio buttons.
- Added blood-drip accents, a copper blood moon and graveyard silhouettes.
- Preserved native keyboard operation and high-contrast control fallbacks.
- Replaced repeating pumpkin/ghost scenery with original SVG moonlight,
  silhouettes, bats and bare autumn trees.
- Lightened the header to a warm amber gradient with subtle cobweb artwork.
- Reduced category title bars and removed their repeating decoration.
- Recoloured all search inputs, text fields, selects, textareas and autofill.
- Changed the footer author credit/link to Halloween — Spiderpiggy Trivia,
  https://spiderpiggy.com.
- Replaced cartoon overlays with subtle bat silhouettes confined behind
  header content; the editor and text are never covered by decoration.
