"""Writes a shelf card that marks its lines the three ways a text can be marked. The Python twin of the `write_text_ornaments` example in Rust. A rule under the words, a rule through the letters, a rule over the top: the engine takes all three from the font rather than from a coordinate, so they follow whatever size the text is set in. The heading and the mark across the foot each carry a shadow — the same words set once more, offset and paler, under the words themselves. The heading's letters are pushed apart and the standfirst's narrowed, both counted where the lines are broken. The back of the card sets the rest of what spaces a text: the words of one line pushed apart, one paragraph set close and then set wide, a figure lifted above the line to call a note, and the mark's words drawn hollow. Word spacing moves the pen only at the byte a one-byte encoding gives the space, so the face is added a second time, reached through such an encoding, for the one line that shows it. Its last part rules a plain paragraph: one line underlined, then hollow words set on a band laid down before them. A third page paints one word each of the four ways a text can be painted without clipping what follows: filled, outlined, both, and not at all. Every word is held in `Words`, once per language, and `HQF_PDF_LANG` picks which set is set. The prices are not words: they stand in one table, shared by both languages.
