css: .row style guide + conditional templates — fix 'log out' breaking + note overlap

The previous .row rule unconditionally pinned column 2 at 1fr, which
stretched whichever child happened to land there. On the screenshot
that meant the 'log out' button got stretched and wrapped its label
across two lines, and the trailing note overlapped buttons it was
supposed to describe.

New rules (now also documented in CLAUDE.md as a style guide so future
authoring is consistent):

- default .row: grid-auto-columns: max-content (everything packs at
  its natural width, no stretch)
- :has(> :first-child + input/select): template 'auto 1fr', input grows
- :has(> input/select:first-child): template '1fr', input fills, rest pack
- .row > .note: auto-drops to its own line under the buttons/inputs via
  grid-column: 1 / -1
- .row > label: white-space: normal, so long checkbox labels wrap

Applied to zebra-spaces, chat, zebra-audio. CLAUDE.md "Web style
guide — form-row patterns" table lists every supported shape so new
rows reuse the primitive instead of inventing custom layouts.

 (e.g. a label + a value), grid still works fine
 (`grid-template-columns: auto 1fr`). Don't reach for flex.
 
+### Web style guide — form-row patterns
+
+`.row` is the single primitive for every horizontal form strip in every
+zebra page. Don't invent new wrappers. CSS auto-detects the row shape via
+`:has()` and picks the right grid template.
+
+Supported row shapes (DOM order matters):
+
+| Shape | Template applied | Use when |
+|---|---|---|
+| `<button> <button> ...` (no input) | `grid-auto-columns: max-content` (default — pack) | "stop sharing" + "stop camera" + select-camera; vault buttons |
+| `<label> <input>` or `<label> <select>` | `auto 1fr` (input cell stretches) | handle row, mic-input row |
+| `<label> <input> <button>` | `auto 1fr` + extra cells packed | rare; same template as above + a trailing packed cell |
+| `<input> <button>` (input first) | `1fr` (input fills, button packs after) | rendezvous code + enter; password + export; share URL + copy |
+| anything + `<span class="note">` | the `.note` is auto-placed on its own row beneath via `grid-column: 1 / -1` | descriptive subtext after buttons |
+
+Rules:
+
+- Never put inline `style="flex:1"` on a row child. Use `.row` and trust
+  the template selector.
+- Don't add a stretchy `<div>` to fake spacing. If you need a button
+  group on the right, append the buttons as siblings — they'll pack
+  right of the stretchy cell.
+- A `<span class="note">` inside `.row` *always* drops to its own line.
+  If you want note text on the same line as a button, use a different
+  class (e.g. inline `<span>`).
+- Long checkbox labels get `white-space: normal` automatically, so a
+  music-mode-style "raw mic, no echo/noise cancellation (for playing
+  audio through it)" wraps cleanly inside its column.
+
+If a new row shape doesn't fit the patterns above, add the case to this
+table and add the matching `:has()` selector — don't reach for inline
+styles or flex.
