Patch Changes

• 79c9872: Assemble class names without the throwaway arrays.

  Every style leaf of every css() cache miss built an array for the prefix, filtered it and joined it — and most
  configs set no prefix, so that array only ever held the class it started with. Conditions were spread into a second
  array and joined even when there were none.

  • A flat css() cache miss end to end: 1710 → 1443 ns (-15.6%)
  • One with conditions and a responsive value: 2675 → 2589 ns (-3.2%)
  • Measured on the assembly alone, with the memo forced to miss: +25% flat, +10% with a condition, +14%
    with a condition and a prefix
  • Class names are unchanged across a 27,000-object corpus, and across 43,008 combinations of prefix, class, condition
    and hashing

  The prefix is now read once when the css function is built rather than per leaf. It is set in the Utility
  constructor and the utility:created hook can only replace toHash, so there is nothing to re-read.

• 61fe88c: Answer "is this style object empty" without building the compacted object.

  mergeCss discards style objects that hold nothing once undefined values are dropped, and it decided that by
  compacting the object, taking a key array for the result, and throwing both away. It only ever needed to know whether
  one defined value existed.

  • The predicate itself: 19x on a three-key style object, 43x on a twenty-key one
  • A flat css() cache miss end to end: 2030 → 1857 ns (-8.5%); the nested case moves within noise
  • Class names are unchanged across a 27,000-object corpus

  The predicate is the same one: Object.keys enumerates exactly what compact's Object.entries did, so own,
  enumerable and string-keyed still decide it, and null still counts as present where undefined does not.

• be3764d: Skip the per-leaf string rewrites that have nothing to rewrite.

  sanitize, isImportant, withoutImportant and withoutSpace run on every style leaf of every css() cache miss,
  and each one starts with a regex rewrite. For the values that dominate real style objects — red, 4px, lg — all
  four are no-ops. Each now begins with the cheapest search that can prove there is nothing to do.

  • A flat css() cache miss: 2474 → 2027 ns (-18%)
  • One with conditions and a responsive value: 3040 → 2808 ns (-7.6%)
  • Class names are unchanged across a 27,000-object corpus covering conditions, responsive arrays, !important, and
    values carrying whitespace

  The guards are exact rather than approximate, which is the only thing making them safe: /\s/ is precisely the class
  the collapse matched, trim() strips precisely that set again, and /\s*!(important)?/ cannot match a string with no
  !.

  withoutImportant and withoutSpace now declare string | T instead of inferring it. They return a rewritten
  string, so inferring T would have promised callers back the literal they passed in.

• 7a63215: Stop rebuilding style objects that are already normal.

  Normalizing renames a shorthand to its longhand, expands a responsive array into a breakpoint object, and drops
  nullish leaves. A flat object of plain values written in longhand needs none of the three — which is most of what
  css() is handed — but it was still walked and rebuilt, with a path array allocated per key.

  • Normalizing a flat object, measured through mergeCss: -22% to -26%, and -28% for one carrying twenty
    properties
  • A flat css() cache miss end to end: 1825 → 1685 ns (-7.7%)
  • Class names are unchanged across a 27,000-object corpus

  An object that does need normalizing pays for the check that found out, which measures between +2% and +7% depending
  on how late the first dirty key appears. The nested case is around -4% overall, since the same objects tend to have
  flat blocks inside them.

  The result may now be the argument itself rather than a fresh object, so callers have to treat it as read-only. Every
  one already does: merging accumulates into its own object, and css.raw() and cva.raw() clone at the boundary.

• 2130606: Call splitProps predicates with the key alone.

  The predicate was handed straight to Array.prototype.filter, which calls it with (key, index, allKeys). A
  one-parameter predicate cannot see the extra arguments, but a memoized one reads its whole argument list — and the
  predicate the JSX factory passes is isCssProperty, which is memoized. So the memo hashed the entire key array once
  per prop, and keyed its cache on it: two elements with different prop sets shared no entry even for the same prop
  name.

  Every styled element pays this, once per prop, on every render.

  • splitProps with a memoized predicate: 6.0x faster
  • A React SSR render of styled elements: 4.18 → 1.15 µs per element (3.6x)
  • The same for elements with a cva config: 11.2 → 2.17 µs per element (5.2x)
  • Markup and splitProps output are unchanged

  Predicates have always been typed (key: string) => boolean, so no typed caller could have read the extra arguments.
