Ported fromd719fb77(#1717); the hatch draw-order, PDF and recovery-settle hunks stay out (main owns those paths). - La16 was still billed at 4 B/px: the no-conversion special case keyed on native_bpp == 4, which La16 also is — but only Rgba8 is a real move in into_rgba8, so La16's decode peak is 8. The case now keys on the color type, and a table test pins every layout's peak (plus GIF's screen+frame 8) so the accounting can't silently drift. - json_values_match: an integer beyond f64 precision no longer matches a float it merely rounds onto; a mixed pair matches only when the float is whole and converts back to exactly that integer (also the fuzz finding of9262d63f). - ocs-control.js resolves `ready` with the API object instead of window.ocsControl, which is still undefined when the bridge already exists as the script runs (built before the first settle, avoiding the temporal-dead-zone throw of a later const); DATALINK on web says the typed path is superseded by the picker instead of silently discarding it.

// Web automation convenience API (#1349).
|
|
//
|
|
// The wasm module exposes the control bridge through `window.wasmBindings`
|
|
// (ocs_control_submit / ocs_control_take). This module wraps it in promises:
|
|
//
|
|
// await window.ocsControl.ready resolves once the bridge exists
|
|
// window.addEventListener("ocs-ready", …) fired once, at the same moment
|
|
// await window.ocsControl.request({...}) one control request -> final reply
|
|
//
|
|
// Hosts that intend to automate from the start should set
|
|
// localStorage["opencadstudio.automation"] = "1" before the page loads so the
|
|
// startup donation prompt never appears (see docs/automation/web.md).
