Render the explicit-class variant as an <a> badge (reference parity) so
it inherits the card font instead of the UA button stylesheet, and add
the reference icon spacing (ml3 mr6). FA5 fa-calendar-check retained;
the header dropdown keeps its <button> runtime.
The level (等级) badge was wrapping to its own line below the username and
rendering at the intrinsic PNG size in most surfaces. Centralize the badge
sizing after zibll's `.img-icon` (height: 1.1em, inline-block) in base.css so
every route gets the same compact inline badge, and keep the name row from
flex-wrapping.
- Add shared `.aksrt-user-level-icon / .aksrt-identity-medal` rule + nowrap name
rows in base.css (loaded on all routes).
- Header dropdown: append the level icon next to the display name (was a
separate badges row); constrain the name to ellipsis so the badge never wraps.
- User center profile header & author hero: render the level icon inside the
<h1> name row; drop the duplicate level chip from the signals row.
- Single article author bar / after-box author card: nowrap the name row and
size the level icon to 1.2em (was unstyled → intrinsic PNG size).
- Comments: inner <name> nowrap with a name clamp; medal sized to 1em.
- Consolidate the per-route `.aksrt-user-level-icon` duplicates in
user-center/level.css and profile/layout.css onto the shared rule.
