Convoa 0.6.31 — original artwork Night Shift edge patch

Upload patch files into your forum root, preserving paths, then purge the phpBB
cache (ACP > General > Purge the cache) and refresh your browser.
No database changes or smiley re-import needed.

Night Shift now retains the original day-view forum/topic/PM artwork, colours,
state markers and dimensions. A one-pixel SVG edge filter reduces near-white
fringing next to transparency without recolouring the interior. Emoticons use
the same filter, without the previous desaturation or pale drop-shadow.
Original GIF files are unchanged. Smiley GIF animation is retained.
Day view is unchanged. The existing switch and saved preference still apply.
The smiley picker and popup use the same settings.

Validated: native status mappings, SVG parsing, original asset equality and ZIP
integrity. Live PHP/database testing requires the deployed forum.
