+** v1.1.0: SGR Mouse Event Parsing
+
+DONE. ~read-event~ now decodes SGR extended mouse sequences
+(~ESC[<Cb;Cx;CyM/m~) into structured ~mouse-event~ structs, where previously
+they fell through as ~:unknown~ key events and printed as control characters.
+
+What was added:
+- ~%read-digits~ — reads multi-digit numeric parameters from raw terminal
+  bytes, handling arbitrary-length values (e.g. coordinates > 99)
+- ~%parse-sgr-mouse~ — full SGR mouse decoder: button code → keyword
+  (~:left~, ~:middle~, ~:right~, ~:scroll-up~, ~:scroll-down~, ~:drag~),
+  press/release detection, 1-based → 0-based coordinate conversion
+- ~parse-csi-sequence~ detects the ~~<~~ marker byte (0x3C) and delegates
+  to ~%parse-sgr-mouse~ instead of treating the sequence as keyboard input
+
+The mouse enable/disable sequences were already sent by
+~initialize-backend~/~shutdown-backend~ (lines 126-128, 139-141 of
+~modern.lisp~). The parsing gap was the only missing piece.
+
+Test coverage: 461 unit tests + 32 integration tests, all at 100%.
+Org source: ~org/text-input.org~ (tangled to ~src/components/input.lisp~).
