### Description

In light mode dank16 `color3` measures about 3:1 against the light background (`#998e00` on `#f5fafc`, 3.21:1), so yellow text in terminals is hard to read. Man pages rendered through bat and fzf's counters use it heavily.

**Cause**

- The light branch picks `color3` with `ensureContrastBidirectional(…, accentTarget, …)` ([dank16.go:573](https://github.com/AvengeMedia/DankMaterialShell/blob/f864dc22338e3f5c81f14478f4566f6a1717f982/core/internal/dank16/dank16.go#L573)); the dark branch uses `ensureContrastAuto(…, normalTextTarget, …)` ([dank16.go:628](https://github.com/AvengeMedia/DankMaterialShell/blob/f864dc22338e3f5c81f14478f4566f6a1717f982/core/internal/dank16/dank16.go#L628)).
- It is independent of the background issue: generating the light palette against the light surface gives the same `#998e00`.
- If the lower target is deliberate to keep the hue recognisably yellow, it still leaves yellow text below the normal-text target the dark branch uses (4.5:1 in its WCAG path).

Reproduced on 5 wallpapers: 2.88–3.21:1.

### Expected Behavior

Light yellow meets the same normal-text target that dark mode uses.

### Steps to Reproduce

1. Use a wallpaper-based dynamic theme in light mode.
2. Check `color3` in the generated kitty theme, or `.color3.light` from `dms dank16 --variants …`.

### Error Messages/Logs

_No response_

### Screenshots/Recordings

_No response_

Start in core/internal/dank16/dank16.go at the light and dark color3 paths around lines 573 and 628, and compare their contrast-target handling. Run dms dank16 --variants … and inspect .color3.light or the generated kitty theme across wallpapers. Done means light-mode color3 meets the normal-text contrast target described in the issue.
