accordion: tone down open-trigger highlight (no pink text)

The open accordion trigger was rendering in `--color-primary-text`
(pink/magenta in dark theme), which read as a loud accent on the
heading — visually noisy and inconsistent with shadcn-svelte / Radix
/ Ark UI, which all keep the trigger text in the regular content
tone and let the rotated chevron + revealed content signal "open".

Recipe tokens updated:

- `accordion.trigger-color-open`: `--color-primary-text` →
  `--color-content-primary` (no recolor on open).
- `accordion.indicator-color-open`: `--color-primary-text` →
  `--color-content-primary` (subtle emphasis without the loud
  accent).

`generated/base.css` regenerated. Verified in browser: open trigger
heading now matches the closed triggers' tone; the chevron rotates
upward and the content reveals as the only open affordances.
