R20 — 23 September 2026
- Rename navigation links: Question → Motivation; Explore → Examples; Geometry → Proof ideas.
- Preserve the original anchor targets, body text, section order, equations, graph code and independent closed-by-default panels.
- Refresh website and offline packages; no live deployment.

R19 — 22 September 2026
- Keep the GKM section title and its introductory explanation visible at all times.
- Independently collapse Description: vertices, edges, and labels; and Example: filter edges, then vertices.
- Both panels are initially closed. Either, neither, or both may be open.
- Section/navigation links show the introduction; deep links reveal only the panel containing the target.
- Retain all existing mathematical text, formulas, citations, graphs, selection state and approved circle styling.
- No new website deployment or public revision badge.

R18 — 22 September 2026

The graph-construction section is now closed by default, retaining its +/− disclosure and anchor behavior.
Replaced “Schubert interval” by “Bruhat interval” throughout the research page.
The lead now identifies the intersection graph as the induced subgraph on its T-fixed point set [w,w_0].
Preserved the order Motivation → graph construction → Main result → Interactive examples; aligned the navigation.
Regenerated the offline ZIP from the same current site files.
Graph logic, mathematical results, references, and the approved circle styles are unchanged.
This is a local build, not a live website deployment.
