* cg-core.el (cg-ai-level): new difficulty defcustom. (cg-red-suit-p):
return a normalised boolean so two red suits compare equal by colour --
diamond and heart were wrongly treated as opposite colours, letting a red
card build on another red card in the alternating-colour games.
* cg-crapette.el (cg-crap--ai-greedy-move, cg-crap--ai-play): honour easy
/ normal / hard.
* cg-trick.el (cg-trick--run): easy plays a random legal card.
* card-games.el (card-game): clickable AI-level control.
(card-game--cycle-ai, card-games-set-ai-level): change it.
* test/card-games-tests.el: cgt-red-suit-boolean, cgt-ai-level-easy-crapette;
bind cg-ai-level in cgt-crap-ai-enabling.
* NEWS.
* cg-trick.el (cg-trick--svg, cg-trick--draw-backs): draw the whole table
as one SVG -- three opponents, the trick in a diamond, the South hand
fanned with cursor, legal-play hints, and pass marks; hand cards carry
(hand . INDEX) click regions. (cg-trick--render-text): the text fallback.
(cg-render): dispatch SVG on a graphical display, else text. Add a footer
legend; refresh the help. Covers Hearts, Spades, Whist, Oh Hell, and the
Euchre/Pitch/Briscola subclasses.
* test/card-games-tests.el: add cgt-trick-svg-smoke, cgt-trick-svg-bidding.
* NEWS: note the trick-taking SVG table.
* cg-crapette.el (cg-crap--house-move): honour an optional WANT count on
an empty-house destination. (cg-crap--do-move): thread it through.
(cg-crap--hold-adjust, cg-crap-hold-less, cg-crap-hold-more): [ and ] set
the held count. (cg-crap--holding-line): show the run with the held
cards marked. (cg-crap-act): default the held count to the run length.
Bind [ and ]; update the legend and help.
* test/card-games-tests.el: add cgt-crap-sequence-partial, cgt-crap-partial-space.
* NEWS: note choosing the group size.
* cg-crapette.el (cg-crapette-stops): new defcustom.
(cg-crap--stop): call STOP (end your turn) or block, per the custom, when
you skip an available foundation play; wired into drop, draw, and end.
(cg-crap--builds-down-p, cg-crap--house-run, cg-crap--free-houses,
cg-crap--capacity, cg-crap--house-move, cg-crap--do-move): move a legal
sequence between houses, limited by the number of empty houses.
* test/card-games-tests.el: add cgt-crap-house-run, -sequence-move,
-sequence-space, -stop.
* NEWS: note the stop rule and sequenced moves.
* cg-crapette.el: new game on cg-core — eight foundations (up by suit,
two decks), eight shared houses (down, alternating colour), per-player
reserve/waste/hand; foundation priority; loading onto the opponent; a
greedy AI; text UI with cursor pick/drop, undo, and q-to-menu.
* card-games.el: require cg-crapette and add the chooser entry.
* Makefile (EL): add cg-crapette.el.
* test/card-games-tests.el: 5 ERT (deal, legality, win, AI turn, AI foundation).
