Why

Moli's Markdown export distinguishes an inherited page-loading veil from an explicit hidden subtree. Only the resolved cascade can tell whether the element establishes its own visibility value after variable substitution and cascade rollback.

Change

Record HAS_OWN_VISIBILITY when the winning declaration is applied. This is a read-only style fact; consumers do not parse stylesheets or repeat the cascade.

The base is moli-update-main-20261018, the Stylo revision already pinned by Moli main (973988b9). The diff contains only the flag and its cascade assignment. The earlier animation-opacity API has been removed because current document export does not use paint effects to select source content.

Consumer and validation

Moli #1337 consumes the flag in a single style-observation batch. Its page-export tests cover inherited visibility, explicit hidden descendants, variable substitution, cascade rollback, disclosure panels and ordinary article siblings. All 28 Markdown renderer tests and affected-crate Clippy pass against this revision; the published historical benchmark remains bound to its original binary.

更正此前“已归并到 #1、#2 重复”的说明：复核后确认两项 PR 解决的是不同问题。#1 是 preferred text scale 环境支持；本 PR #2 提供 Moli #919 实际需要的 resolved visibility / final opacity content provenance，不能由 #1 替代。

本 PR 已同步 Stylo moli 当前提交，最新 head 为 1032a2947ec2f7cee1027d07084203be87e17643，Linux debug/release、macOS debug、Windows debug 与汇总门禁均通过。Moli #919 已精确锁定该提交。此前评论作废，以当前 PR body 与本条更正为准。
