fix(theme-studio): make the color picker stand out from the page

The picker panel's background (#161412) sat a few shades off the page background (#0d0b0a), so it was hard to tell apart from the page. I gave it the studio's gold accent border (#e8bd30) and lifted the background to #1f1c19, both already used in the toolbar chrome, so the panel reads as a distinct surface. The #pickertest gate asserts the accent border and a per-channel background lift of at least 12 over the page, so the distinction can't quietly regress.

 Craig, 2026-06-11 manual-test walk: the color picker's background is hard to distinguish from the page background. Give the picker panel a visibly distinct background or a highlighted border so it stands out. Pin with a gate asserting the picker element carries the distinct style.
+Done 2026-06-16: the picker now carries the gold accent border (#e8bd30) and a lighter background (#1f1c19 vs the page's #0d0b0a). The #pickertest gate asserts the accent border and a per-channel background lift of ≥12 over the page, so the distinction can't silently regress.
 
 ** TODO [#C] theme-studio: restrict the cursor row to its background :bug:studio:
 The UI table gives the cursor face the full control set (fg, B/I/U/S, box), but Emacs only honors the cursor face's :background. Its shape is cursor-type, not a face attribute, so every other control on that row is a no-op once the theme loads. Restrict the cursor row to just its background swatch so the studio doesn't present controls Emacs drops.

 - Open mu4e, look at the headers list and the main menu
 - Open a message and read the body
 Expected: headers list shows unread/flagged/date/subject in their theme colors (mu4e-unread-face gold, mu4e-header-face green, etc.); the main menu and the message-view headers (From/To/Subject) are themed; the message body still renders correctly (gnus does the body, so it's unaffected). NOTE: a plain "g" refresh in an already-open *mu4e-headers* won't fix it on its own unless font-lock is off there; a restart is the reliable check.
+*** VERIFY theme-studio gnus view package themes the article headers
+What we're verifying: gnus is now its own view package in theme-studio (it drives the mu4e article view), so the bright-green article headers can be themed and exported. #gnustest confirms the package is registered and its preview emits only real gnus faces; this is the visual read plus the live-green retirement.
+- Reload theme-studio (or make theme-studio-open)
+- Pick "gnus (mu4e article view)" from the view dropdown (sits among the g entries)
+- Confirm the preview shows a header block, an emphasized body, an 11-level quoted reply chain, and a signature
+- Theme a few gnus faces (e.g. gnus-header-name, gnus-header-from, gnus-cite-1) to obvious colors, export to WIP.json, then deploy

+- Restart Emacs (or reload the theme), reopen a mu4e message
+Expected: the studio preview renders each gnus face in its theme color; after export + deploy, the *mu4e-article* From/Subject/To/Date headers show the themed colors instead of the gnus green defaults.
 *** VERIFY theme-studio markdown preview reads like a real README
 What we're verifying: selecting markdown-mode in the view dropdown shows a realistic README (not the generic face-name list), and the markdown faces render legibly in context. #mdtest already confirms the wiring + that every element's face is real; this is the visual read.
