Jade's edge-trace hero hand-walked the panel perimeter as straight line
segments, so rounded corners chamfered into flat polygons. Retire it in
favour of the gradient-border effect, which draws via AddRect and hugs
the real corner arcs.
- theme_effects: drawGradientBorderShift gains phaseOffset + alphaMul;
drawPanelEffects now draws it on every glass panel (position-phased so
panels drift like veins at different depths, 0.6x alpha vs the active
nav button), gated behind a new opt-in gradient-border-panels flag so
button-only themes (Obsidian) are unaffected.
- jade.toml: edge-trace off; gradient-border-panels on, speed 0.10,
jade->gold; jade motes + viewport wash/vignette kept.
