Overview

Transforms accordion syntax into wa-accordion / wa-accordion-item elements Primary syntax:

//////appearance? mode? icon-placement? heading:N?
/// [expanded] [disabled] [icon:name] Label text
item body markdown
///
//////
Alternative syntax: :::wa-accordion …same items… :

Container attributes (bare, order-independent, rightmost-wins):

- appearance: outlined (default), filled, filled-outlined, plain
- mode: multiple (default), single, single-collapsible
- icon-placement: start, end (default emitted only when given)
- heading:N -> heading-level="N" where N is 1-6 or "none"

Item tokens (leading flags, then the rest of the line is the label):

- expanded -> expanded; disabled -> disabled
- icon:name -> <wa-icon slot="icon" name="name"></wa-icon> as first child

wa-accordion is experimental in Web Awesome (added 3.7). expanded/disabled and the mode/appearance/icon-placement attributes are all static-safe.
