An inline SVG put every label of both layouts, its title and its desc
into the page text, next to the prose that already says the steps: a
text dump of the Steam Deck tab read the steps three times, glued.
Each drawing is now one SVG file per layout and theme under
assets/diagrams, shown through <picture> with alt="". The figure says
its words once, in one screen-reader line and its caption.
make_demo.py records a second variant: the full-screen interface at the
640x480 screen of an R36S, on an ArkOS root made with bwrap, started as
the Tools menu launcher starts it (RETROBIOS_PAD=gptokeyb), driven by the
keys gptokeyb sends for the buttons. demo.json holds one entry per
variant with its alt text. No Windows variant: under pwsh on Linux the
installer's summary gives --dest /mnt/e/bios back.
The quick install box of Get your files gets an "On the device" tab with
the handheld recording, the terminal recording under the others but
Windows, and, under the text of each computer tab, a drawing of opening
the terminal and pasting (sitesteps.py, inline SVG in the theme's
colours, title and desc). The terminal steps name the physical action.
