docs: lower right-side TOC panel breakpoint to 1280px

[cloud-hai-vo]

Summary

• Lowers the min-width breakpoint for the right-side "On this page" TOC panel from 1380px → 1280px
• Panel was already implemented and wired up; it just wasn't visible on standard 1280px displays
• Applies to all content pages (Advanced Features, Getting Started, API Reference, etc.) — the panel is JS-generated from h2 headings at runtime, no per-page HTML changes needed

Pull request overview

Updates EggMapper docs styling so the right-side “On this page” TOC panel becomes visible on standard 1280px-wide displays by lowering its display breakpoint.

Changes:

• Lowered .toc-panel visibility breakpoint from min-width: 1380px to min-width: 1280px.

[Copilot]

Lowering the TOC panel breakpoint to 1280px causes the fixed right-side panel (196px wide, right: 1.5rem) to overlap the main .content-wrapper at exactly 1280px. With --sidebar-w: 264px and .main-content padding of 3rem, the available right gutter is ~208px at 1280px, while the panel needs ~220px, so content can be covered. Consider either (a) using a slightly higher breakpoint (>=1292px), or (b) adding a media-query adjustment that reserves space when the panel is shown (e.g., increased .main-content right padding / .content-wrapper right margin) or reduces panel width/right offset for 1280–1379px.

Suggested change

	@media (min-width: 1280px) { .toc-panel { display: block; } }
	@media (min-width: 1292px) { .toc-panel { display: block; } }

📝 Notes

• Each benchmark class is decorated with [MemoryDiagnoser] and [RankColumn].
• The global config (see src/EggMapper.Benchmarks/Program.cs) adds Min, Median, and Max columns.
• Manual is the hand-written baseline (ratio = 1.00). A ratio < 1 means faster than manual.
• Benchmarks run on GitHub-hosted runners — absolute times may vary between runs; focus on Ratio for comparisons.
• To reproduce locally:

  cd src/EggMapper.Benchmarks
