Major coverage improvements:
- safehttp: 46.7% -> 93.3% (SafeDialer, redirect checking, SSRF protection)
- api: 81.8% -> 96.4% (HandleImport 0% -> 100%, stream errors, content types)
- importer: 85.3% -> 94.7% (ImportFeeds dispatcher, OPML nesting, edge cases)
- cmd/neko: 77.1% -> 85.4% (purge, secure-cookies, minutes, allow-local flags)

New tests added:
- Security regression tests (CSRF token uniqueness, mismatch rejection,
  auth cookie HttpOnly, security headers, API auth requirements)
- Stress tests for concurrent mixed operations and rapid state toggling
- SSRF protection tests for SafeDialer hostname resolution and redirect paths

Swap the single cycle button for individual emoji per theme:
○ Default, ◆ Refined, ▮ Terminal, ❧ Codex, ❀ Sakura.
Active theme gets a highlighted state. Separated from the
light/dark toggle with a thin divider.

Refined: softer dark-mode link color (#a0c4e8), fix export button
vertical alignment with inline-flex, tighten settings page spacing
(reduce gaps from 3rem to 1.5rem).

Terminal: switch accent from cyan to green (#4ae54a dark / #1a7a2e
light), add proper light mode with pale steel background, scanlines
only in dark mode.

Sidebar: add quick-access controls in footer — moon/sun icon toggles
light/dark, circle icon cycles through style themes showing current
name. Both update reactively on state change.

Add THEMES.md with full documentation on creating new themes:
variable reference, selector guide, light/dark mode tips, and the
registration process.

Adds a style theme system that layers additional CSS files on top of the
base stylesheet. Themes are loaded/unloaded dynamically via <link> tags.

- Default: existing look, unchanged
- Refined: typographic rhythm fixes, consistent spacing on settings page
- Terminal: monospace, dark phosphor CRT aesthetic (scanlines, cyan glow)
- Codex: book/Tufte-inspired with warm paper tones, serif type, fleurons
- Sakura: Japanese-inspired calm aesthetic (named for neko = cat)

Each theme supports both light and dark mode. Style selection persists
in localStorage and is independent of the light/dark toggle.
