/* COA Vault — minimal accordion. Structure only: hairline dividers, padded tap
   targets and one consistent chevron; type and colour are inherited from the theme.
   No cards, rounded corners, tints or colour, and no JavaScript — the disclosures
   and the single-open archive are native <details>/<summary>. Override any class
   to restyle. */
