Autosort: Toggle ⇊|⇅ (sorted|default).
Indicator position: Toggle ⇱|⇲ (top|bottom), ⇱ dodges the year in corner (outdated pic); stands out more and stays visible on fics collapsed by @Min_'s Kudosed-history. Toggles do not need reloading. Colors have automatic dark mode.
Dimming: Applied to low-confidence, default is kudos<5 && bookmarks<3 && collections<1. It will not be dimmed if at least one of those is greater or equal. Can modify it atop the code to hide more fics, but disable updates. Dimmed fics are sorted at the end.

v2.3: Switched to GAM score {Bk,Col/Ku} instead of Polynomial score {Bk,Col,Com/Ku}.

v2.0:
• Log() Engagement metrics (bookmarks/collections/comments/kudos) selected due to high correlation with my top favorite fics. By comparison the classic (x/hits) metrics feel completely random:

• 2nd-degree polynomial quantile regressions (P10, P50, and P90) of the 3 selected metrics pairs:
For each pair, an individual score is computed by:
    ◦ Deriving a skewed normal distribution from the polynomial contours.
    ◦ Z-score calculation based on its deviation from the P50 center-line.
    ◦ Converted into a 0-100 inverted percentile rank via NCDF.

• Final score == Max of all 3 reliable scores, gated by minimum stat counts.
The score is mapped to a perfect 0-100 percentile rank via ECDF normalization for uniform scoring.
