Frontend polish: search surface hierarchy, CTA interaction consistency, timeline readability

[Copilot]

This PR addresses the requested frontend polish pass by focusing on high-impact aesthetic refinements (not feature work): stronger visual hierarchy, tighter micro-interactions, and better cross-theme readability. Changes are scoped to existing UI surfaces and documented in both changelogs for 2026-05-17.

• Search/Filter Surface Refinement

  • Elevated .search-container into a distinct, theme-aware surface with tuned border, layered gradient background, and subtle depth.
  • Added light-theme-specific treatment to avoid flat inversion and preserve contrast character.

• Primary CTA Interaction Harmonization

  • Unified motion/shape behavior for .export-button and .comparison-button (radius, timing, hover lift).
  • Added explicit :focus-visible treatment for clearer keyboard affordance while keeping interaction feel consistent.

• Timeline Readability Polish

  • Rebalanced timeline metadata typography for scanability:
    • tighter date sizing/tracking
    • improved description line-height
    • cleaner file metadata legibility.

• Changelog Updates

  • Added Day 64 (2026-05-17) entries to:
    • README.md
    • public/README.md

/* CTA harmonization */
.export-button,
.comparison-button {

  transition: transform 0.2s var(--ease-out), box-shadow 0.2s var(--ease-out), filter 0.2s var(--ease-out);
}

.export-button:hover,
.comparison-button:hover {
  transform: translateY(-2px);
