In `@README.md`:
- Around line 129-143: The fenced code blocks in README.md around the three
launch examples (the blocks containing "OCR4Linux",
"~/.config/OCR4Linux/OCR4Linux.sh", and "./OCR4Linux.sh") lack blank lines
before and/or after them; update the file so there is an empty line immediately
before each opening ```sh fence and an empty line immediately after each closing
``` fence to satisfy markdown linting and ensure correct rendering.
- Around line 297-325: The two indented headings "### Example for `Hyprland`
users:" and "### Example for `dwm` users:" are causing markdownlint warnings;
remove the leading spaces so the headings start at column 0 (or alternatively
replace them with bold text like **Example for `Hyprland` users:** and **Example
for `dwm` users:** if you want to keep indentation), and ensure any other nearby
headings in the same block follow the same pattern so markdownlint stops
flagging them.
