"""The research-note design system, lifted verbatim from the published note.

Source of truth: the artifact "NVIDIA T2 FY2027 Readthrough"
(https://claude.ai/code/artifact/a552e2bc-add9-48ea-b706-4b95f122d0e5).

Every colour, font stack, size, weight, border and breakpoint below is the
artifact's own value, copied unchanged. The only transform applied is a
``.rt-note`` prefix on each selector: Streamlit ships base styles for ``p``,
``h1``, ``ul``, ``table`` and friends that are class-scoped and would
otherwise win on specificity. Scoping the note lets the artifact's bare
selectors keep their values and still beat the host page.

Three exports:

``FONT_IMPORT``  the artifact's three families, by @import instead of <link>.
``TOKENS``       the artifact's ``:root`` palette, deliberately *not* scoped —
                 the app chrome reads the same variables, which is what makes
                 the two halves one design.
``NOTE_CSS``     the note itself, masthead through footer.

**Never write an angle bracket in this file's CSS, comments included.** The
stylesheet reaches the page inside a ``<style>`` element; a ``<`` in a comment
is read as the start of a tag and truncates the element there, silently
dropping every rule after it — and, because the app concatenates this
stylesheet with its own chrome CSS, everything after it too. A comment
mentioning the svg tag once cost the whole page its layout.
