- Status tables: the whole header (column names + filters) sticks as one
block, tucked 1px under the group header, so no gap can open between
the rows; offsets use fractional heights
- Phones/tablets: the filter panel sticks under the group header too, and
is opaque and compact (three filters per row on phones)
- Custom View: fix the group header being pushed over the column header
(it lives inside the view's own scroll box); the column header now pins
to the top of that box on desktop, and the header strip sticks on phones
- All Devices: group title is "All Devices (N)" instead of "Missing
Software", matching the page title count
- Documentation fits the window on desktop: only the article list and the
article scroll; placeholder no longer says "from the left"
- Dialogs sit above the terminal dock so it can't cover their last rows;
page bottom padding follows the dock's measured height
- Status group headers ("Not Started (37)") stick under the top nav while
scrolling through their group, on every screen size
- On desktop the column header and filter rows stick beneath the group
header (table wrappers no longer clip them; these fixed-layout tables
never scroll sideways at desktop widths)
- layout.js measures the nav, group header and header row heights so the
sticky rows stack without gaps, re-measuring on re-render/resize/scroll
- Phones: the Advanced/Simple View button sits on its own line under the
device name instead of floating over the dialog content
- Rename mobile.css/js to layout.css/js now that they hold desktop rules
