v0.71.0

Added

• Page-level status bar toggle. The dashboard editor now has a
  "Status bar" section below the corner-radius slider. Flip the
  switch and Tesserae auto-inserts a full-width 48 px
  tesserae_status cell at the top of the layout; existing cells
  shift down and rescale proportionally to fit the remaining space.
  Flipping it back off removes the bar and reverses the rescale so
  the layout returns to its pre-toggle shape. Switching layout
  presets while the bar is on preserves it at row 0 rather than
  remapping it into the preset's first slot. Always horizontal at
  the top regardless of panel orientation.

Fixed

• Status bar widget: icons now render on the compose canvas.
  Phosphor's .ph-bold class rules live in the compose document,
  which the shadow root doesn't inherit, so the chip icons were
  rendering as blank squares. The widget now links
  /static/style/spectra-widgets.css into its shadow root, same
  pattern the weather widgets use.
• Status bar widget: text scales with the cell. Font sizes are
  now driven by container-query height units (cqh) with clamps at
  each end, so a 48 px bar and a 400 px cell both render at the right
  weight instead of shrinking to 12 px everywhere.

Removed

• Status bar widget: weather chip and the two custom text slots
  dropped. Weather was misleading in a widget that has no live
  weather source of its own; the custom slots duplicated existing
  widgets. If you were relying on either, drop a
  weather_now widget or a small text widget onto the dashboard
  directly.
