v0.5.0a4 - 2026-05-16

Fixed

  • Panel blank in frontend: the css tagged-template shim in better-todo-panel.js was missing the styleSheet getter that Lit 3 requires when using the Constructable StyleSheets API (adoptedStyleSheets). In every modern browser supportsAdoptingStyleSheets is true, so Lit's adoptStyles called s.styleSheet! on the shim object, received undefined, then adoptedStyleSheets = [undefined] threw a TypeError. That prevented the shadow root from ever being created, leaving the panel completely blank even though its sidebar entry was registered correctly. The shim now lazily constructs a CSSStyleSheet via the getter, matching Lit 3's own CSSResult behaviour.
