\usepackage{iftex}


\ifpdftex
% pdfLaTeX does not support directly embedding OpenType fonts
% We will therefore use fonts from the LaTeX font catalogue
% https://tug.org/FontCatalogue
% These fonts are pdfLaTeX ready
% We use OpenSans as Sans Serif and Caladea as the Serif font
\usepackage[defaultsans,scale=0.9]{opensans} % replaces default sans-serif font
\usepackage{caladea} % replaces default serif font
\usepackage[T1]{fontenc}
\usepackage{unicode-math}  % for \oiint command (also loads fontspec)
\fi


\ifxetex
% XeLaTeX directly supports OpenType fonts
% Use XeLaTeX if you would like more options with fonts
% We use OpenSans as Sans Serif and IBM Plex Serif as the Serif font
% We also augment them with Playfair Display SC for the Small Caps Style.
\usepackage{fontspec}
% The commands \setsansfont, \setmainfont and \setmonofont are provided by the fontspec package.
% These commands provide a very fine grained control over fonts.
% e.g. OpenSans does not provide SmallCapsFont, so we will augment it with Playfair Display SC for the Small Caps Style.
% Small Caps style is used in the pseudocode.

% By default Beamer uses Sans-Serif mode and the font specified in \setsansfont is the font that will be applied in most places.
\setsansfont{Roboto}[
    Path=./fonts/,
    Scale=0.9,
    Extension = .ttf,
    UprightFont=Roboto/*-Regular,
    BoldFont=Roboto/*-Bold,
    ItalicFont=Roboto/*-Italic,
    BoldItalicFont=Roboto/*-BoldItalic,
    SmallCapsFont=Playfair_Display_SC/PlayfairDisplaySC-Regular % OpenSans does not have an SC variant
]
% Other less common font styles are SlantedFont, BoldSlantedFont, SwashFont and BoldSwashFont.
% If your font also provides additional faces (e.g. ExtraLight, etc), fontspec also supports them.
% Please see the fontspec documentation Section 4.3 (Choosing additional NFSS font faces) for details.

% This is used if we use \usefonttheme{serif} in main.tex
% With the default \usefonttheme[onlymath]{serif}, this will control the font used for math
\setmainfont{IBMPlexSerif}[
