"""The design's markup, rendered from state.
This module is the visible layer of the app. Every element here is the
design's own element with the design's own inline styles and token values --
not a Gradio component with CSS applied over it. Gradio owns the transport
(a hidden textbox, a hidden button, one HTML sink) and nothing that is seen.
Reading order matches the design top to bottom: sidebar, header, title row,
stat band, filter rail, model table, right rail, footer, drawer.
Two rules that are not negotiable:
**Everything interpolated is escaped.** Model ids, authors, licences, red-flag
text and training-data summaries all originate from model cards written by
strangers on the internet. They arrive here as data and are escaped on the way
into the page -- `e()` for text, `a()` for attribute values. A red flag reading
`<img src=x onerror=...>` must render as characters, not as an element.
**Nothing is invented.** Where the design shows a number the Atlas cannot
know -- a download trend before two snapshots exist, a market price -- the slot
renders an em dash or is filled with something the index actually knows. The
design is the authority on layout; it is not a licence to fabricate data.

"""The whole page, assembled from one render pass over `view`.
`view` carries everything the renderers need that is derived rather than
stored -- the filtered rows, the hidden count, the trending list -- so
each section is a pure function of (index, state, view) and the filtering
runs once per request rather than once per section.
## No forced `vh` on the root
The root deliberately has no `min-height:100vh`. huggingface.co embeds a
Space in an `<iframe scrolling="no">` and sizes it from the app's reported
content height, so a root that forces its own height from `vh` feeds back:
iframe grows -> 100vh grows -> content reports taller -> iframe grows. It
ratchets, and the visitor sees a page that scrolls forever into empty
space. Measured here at 3890px against ~2100px of real content.
The canvas background is painted on `html, body` and `.gradio-container`
in bit_ui.theme instead, which is what the `100vh` was really for.
`theme.find_forced_vh()` and the test suite keep it out.
