feat: visual polish, focus-point cropping, blurhash placeholders (Release 8)

Browse Source 
Card styling: softer 8px radius, subtle box-shadow elevation, hover enhancement.
Action buttons: borderless with color-coded hover states via color-mix().
Typography: tighter line-height (4/3), larger avatars (44px), gallery images (220px).
Focus-point cropping: convert Mastodon focus.x/y to CSS object-position.
Blurhash placeholders: decode DC component to background-color on images.

/**
* Blurhash placeholder backgrounds for gallery images.
*
* Extracts the average (DC) color from a blurhash string and applies it
* as a background-color on images with a data-blurhash attribute.
* This provides a meaningful colored placeholder while images load.
*
* The DC component is encoded in the first 4 characters of the blurhash
* after the size byte, as a base-83 integer representing an sRGB color.
