🎨 Palette: Improve pointer focus outline suppression using :not(:focus-visible)

[seonghobae]

💡 What
Replaced :focus { outline: none; } with :focus:not(:focus-visible) { outline: none; } on semantic containers (main, .table-wrap, and .export-block pre).

🎯 Why
Using :focus { outline: none; } completely removes the outline for all focus states if a browser does not support :focus-visible. Using :not(:focus-visible) ensures that we suppress outlines for mouse users while providing a safe fallback that keeps the default outline for keyboard users in older browsers.

📸 Before/After
No visual change for users on modern browsers. On older browsers, keyboard users will now see the default browser focus ring instead of no focus ring at all.

♿ Accessibility
This change guarantees that keyboard focus indicators are never entirely hidden on older user agents, maintaining WCAG 2.4.7 Focus Visible compliance even in fallback scenarios.

Closing this unmerged as a duplicate report-accessibility writer. Fresh comparison against current PR #1002 (36e0bdd71535e56fe1329f31c2cd74d0749c64d8) shows #1002 already owns and tests the same production selectors in python/fast_mlsirm/report.py: main, .table-wrap, and .export-block pre use :focus:not(:focus-visible) while explicit keyboard :focus-visible styling remains; #1002 additionally covers disclosure <summary> focus and report-title trust. #1309 exact head 95f1185de6167e41511280598fa7cb8f5e8f5259 repeats that production change and includes unrelated formatting churn in the same source file plus a .jules/palette.md note. Under single-writer-by-conflicting-scope, keep #1002 as the report-surface landing unit and do not land this duplicate independently.
