The README is written for a stranger: what the device hides behind
modifier combos and why that needs an app at all, what each of the four
tabs does, how the Leitner drill works, how to build and install it, and
a map of the source with the domain and UI split explained.
It also records the four things someone reading the code would otherwise
have to discover: that the combo table is generated from reference/ and
must never be typed by hand, that Entry.id and STORAGE_KEY are
load-bearing for migrating progress off the old version, that
touch-action:none and window-level pointerup are what make chorded
answers possible, and that the domain is pure specifically so it can be
tested - which is how a real bug in the weighted card pick surfaced.
Screenshots show Explore with nothing held beside the same screen
holding SHIFT: three functions becoming thirty-five, pads turning from
numerals into FIX VEL, 16 VEL, CUE and CHROMA. That pair explains the
app faster than the prose does. Captured headlessly at the phone's real
360x735, which needed the held layer temporarily patched in source and
restored afterwards.
Notes the data comes from the SP-404MK2 reference manual v5.50 and that
this is unofficial and unaffiliated with Roland, and points at the
bundled OFL font licences.
