the hover tax is pinned and cut, and a spell-less macro is a button

- a tooltip change costs ~1.3 ms — five whole-interface recomputes, each working as designed: the quad re-convert at 474 µs, the Lua tick at 287, the layout resolve at 200, bevy's `Assets<Mesh>` tax at ~270 and the mesh rebuild at 146 — pinned with new hover probes (a jitter dial, a `WOW_PROBE_HOVER_DUTY` duty cycle so run drift cancels, an `AssetChanged` tax meter), and the layout preamble's two whole-roster scans become lists maintained at the writer (52–83 µs → 1–11)
- the splice compared this frame's entries against last frame's by index, so one inserted highlight shifted the 160 entries behind it and read as "everything changed"; it now aligns on `z` — an identity, not a position — and a `Text` entry that writes only quads became spliceable, so a tooltip change re-converts 22 entries instead of 520 (`convert` +439 µs → +107), with `WOW_UI_SPLICE_VERIFY` running the full conversion behind every spliced frame: 0 mismatches over 1,078
- a spell-less macro is a usable action button, not the 0.4 grey — the reference's usable compute has a dedicated leg answering usable for the bound-spell zero, cross-checked at the bytes in the reference's disassembly — and the button's Name line is written unconditionally from `GetActionText` as the reference does, so the macro's name sits under its icon and a `/cast` of a spell the character does not know now greys, which is also 1.12's behaviour (B340)
- a capture bounds its run in wall-clock seconds, because a frame cap is no cap at the ~1 fps a starved `nextDrawable` leaves — 1800 frames is thirty minutes there — and the teardown backstop runs on every run as a liveness guarantee, carrying the exit code the run asked for; the Multisampling row reads Off / 2x / 4x, since "1x" contradicts the no-multisampling byte both of the reference's enumerators normalise to and the bit-depth prefix was identical on every row
