Javascript

Behold an abomination!

const input = require('fs').readFileSync(0, 'utf-8').toString();
const towels = new Set(input.split(/\r?\n\r?\n/g)[0].split(', '));
const count = (p, t) => [...new Array(p.length).keys()].reduce((acc, i) => [...new Array(i + 1).keys()].forEach(j => acc[j] > 0n && t.has(p.substring(j, i + 1)) ? acc[i + 1] += acc[j] : null) ? acc : acc, [1n, ...new Array(p.length).fill(0n)])[p.length];
input.split(/\r?\n\r?\n/g)[1].split(/\r?\n/g).filter(p => p.length > 0).reduce((acc, p) => { let c = count(p, towels); acc[0] += c > 0 ? 1 : 0; acc[1] += c; return acc }, [0, 0n]).forEach((v, i) => console.log(`Part ${i+1}: ${v}`));
