Cardwright v2.14.0 — contrast-edges border mode

A second way to fix a washed-out black border — one that doesn't have to guess
where the border is.

New "Contrast edges" mode, now the default

The existing border treatment measures how deep a card's dark frame runs and
snaps it to black. That measurement is the part that can go wrong on artwork
reaching the cut edge.

Contrast edges detects nothing. The band is a fixed fraction of the card's
shorter side (8% by default), so there is no judgement to get wrong. Three
things keep it off the artwork:

• Quadratic falloff to the inner edge of the band, so there is no seam.
• Tone weighting — only pixels below 140/255 are pushed, so bright art
  inside the band keeps its brightness.
• A contrast curve rather than a binary snap to black.

The previous behaviour is still there as "Auto-detect", just no longer the
default. Off is unchanged. Three new fields in Export → Image let you dial
the band: edge width, edge contrast and edge brightness.

Reimplemented from the approach Proxxied
uses (MIT). Their code is GLSL; this is a numpy reimplementation, not a copy.

Apply to, per source

New checkboxes decide which catalogues get border treatment at all.
MPC Autofill and card backs are off by default — MPC art already carries a
true black edge, so running the effect over it is risk with no upside.

A per-card override (left-click in the preview) still wins over the source
rule, and the preview now resolves modes exactly the way the export does, so
what you see is what prints.

Note for existing users

The auto mode was renamed, and your saved setting is migrated automatically —
if you had border deepening on, it stays on as "Auto-detect". Switch to
"Contrast edges" to try the new one; they can be compared on the same card.
