Engine v2.8

Engine v2.8

Picture books get a point-and-read moment for young readers. Books made with v2 need no change.

Point and read

• tapWords(things, done) in a film's ask beat (CHAPTER.film): once the narration is over, every thing in the picture turns tappable. A tap hops it, shows its word in large letters beside it and says it (audio/<lang>/w-<word>.mp3), with the music ducked under it. A counter and Continue wait in the corner; Continue lights up once every word has been heard. Seeking or replaying clears it.
• side: 'above' | 'below' | 'left' | 'right' places a word; without it the word goes where it fits on the stage. Hit boxes are at least 120 stage px, a child's finger on a phone.
• The scene's continuous motion runs on while the page waits, so puppets keep breathing and blinking.
• Things that are missing, off the stage or covered by another element are named in the console, not skipped silently.
• The video (export.py) cannot tap: P.tapDemo shows the words one by one while it holds.
• Interface strings in en, ru, zh and ja. A book can set --word-font for its early-reader letters.

Stage tap questions

• The focusable-button logic of the stage tap questions is shared with tapWords; ← / → now start from the focused target. Behaviour is otherwise unchanged.

Checked

• engine/check_tapwords.py (new), check_i18n, check_latex, check_volume pass.
• Full suite: 143 of 144 pass, plus the known, unrelated failure (math-notebook/audit_chapter23, a missing timings file).
• Little Red Riding Hood's meadow scene (/little-red-riding-hood/ch01/) is the reference.
