magenta#424: Tidings: YouTube embeds play again (Error 153)

slvrbckt found that a YouTube tiding's embedded player shows **"Video player configuration error, Error 153"** instead of the video.

**Why:** magenta serves `Referrer-Policy: same-origin` (checked on the live tiding page), so the player's iframe goes to youtube-nocookie.com with no Referer at all, and YouTube now refuses to play without one.

**Fix:** `referrerpolicy="strict-origin-when-cross-origin"` on the one embed iframe (`mood_tiding.html`). YouTube gets `https://magenta.cryptograss.live/` only, never the page's path. Vimeo's player gets the same.

**Checked:** in Playwright, the same video (r-_WGJTNp3o) on a page with `same-origin` policy: the iframe without the attribute shows Error 153; with it, the player loads with the title and play button.
