Deck detail says what the deck can be studied with

[jvsena42]

The four study opt-ins — Listen, Speak, Type the answer, Both directions — were settable at publish
and in the deck editor and shown nowhere else. The reader deciding whether to keep a deck was the
one person who could not find out what it offered.

Deck detail now carries a STUDY MODES row between the tags and the stats bar, one chip per opt-in
the author turned on, reusing the deck editor's own icons and labels so the row names the switches
its author actually flipped. Read-only — these are the author's decisions, not the reader's.

Two things worth knowing

Listen and Speak are folded through speechReady before they reach the screen, as the study
session and the editor already do. A deck with the opt-in on and no declared language pair offers
neither button, so a chip there would advertise a feature the session withholds. Type and Both
directions are ungated, as everywhere else.

All four chips take the primary accent, not the editor's alternating pair. Speak and Both
directions are purple in the editor — but purple on a soft purple pill is exactly what TagChip
is, and the first build put them directly under the tag row where they read as more tags. Orange
says what the deck does, purple says what it is about; the caption is the second half of that
separation.

Verified

Driven on Medium_Phone (staging): one chip, then the language pair added in the editor and the
Listen chip appearing, in light and dark; and on Pixel_Tablet at both the medium and expanded
width classes. ciCheck, detektAll, :shared:jvmTest and checkStringPlurals all pass. Full
run in journeys/RESULTS.md, with journey 26 extended to cover the row and the gate.

iOS is unbuilt — written on a Linux box, so DeckFeatureBadges.swift and its two wiring lines
need a Mac pass before they count as verified.
