v2.7.0

Minor Changes

• #220 e9d04ac Thanks @tenphi! - Add the _ fallback floor key and equalize selector specificity with :where().

  A standalone _ key in a style value map defines a map-wide fallback floor: its
  value always applies and is never turned off by higher-priority states,
  which simply layer over it via the cascade. This fixes the CSS
  three-valued-logic hole where a negated @supports(...) / container-query
  default branch silently never applies (e.g. scroll-state is supported but a
  specific scroll-state(...) query is unknown), leaving no rule active. _ is
  standalone-only — it cannot be combined with state logic (_ & hovered is
  ignored with a dev warning) — and it can coexist with the bare '' default
  ('' is the negated default, _ is the always-on floor).

  To make the additive cascade predictable, every stateful selector Tasty
  generates (modifiers, pseudo-classes, :is()/:not() groups, and
  @root/@parent context) is now wrapped in :where(...) so it carries zero
  specificity. The only specificity anchors are the doubled component class
  (.tXX.tXX) and sub-element [data-element] attributes; overlapping rules
  resolve purely by source order, which Tasty now emits ascending by priority
  (@starting-style last).

  Note: state selectors drop from e.g. 0,3,0 to the class baseline 0,2,0
  specificity. This is intentional — the doubled class remains the floor — but may
  affect overrides from external CSS that relied on state-selector specificity.

Patch Changes

• #220 3c11119 Thanks @tenphi! - Auto-correct and warn on misplaced or redundant default states in style maps.

  The bare default state ('') is the lowest-priority state and must be the first
  key in a state map. When it is authored after other states, Tasty now moves it
  to the front and emits a MISPLACED_DEFAULT_STATE dev warning — previously it
  silently overrode every state above it because a TRUE condition is never
  negated.

  Defining both a _ fallback floor and a bare '' default with no other states
  is redundant: the '' default would always be superseded by the floor. Tasty
  now keeps the _ value, drops the '' default, and emits a
  REDUNDANT_DEFAULT_STATE dev warning. When other states exist, _ and ''
  coexist (one is the always-on floor, the other the negated default).
