Commit 0d477ac (the Terminal token system) pinned both
CARD_SHADOW_ALPHA_IDLE and CARD_SHADOW_ALPHA_DRAG to 0.0 because the
Terminal design system explicitly disallows box-shadow ("depth via
1px borders and tonal layering"). The existing invariant
\`drag_alpha > idle_alpha\` then fails — \`0.0 > 0.0\` is false.
Loosen the assertion to \`drag_alpha >= idle_alpha\` and document the
intent: under Terminal both are 0; under any future palette that
re-enables shadows, drag still must not be weaker than idle. The
useful regression-guard (catching an accidental swap of the two
constants) is preserved.
