(1) **`--duoUser` bg on the saved-sig aperture.** Per user spec — once the table hex is server-side gone (f609313's `{% if not current_significator %}` wrap), the now-mostly-empty olive aperture reads as a distinct mode vs the default landing (--priUser bg w. hex). New `.my-sign-page[data-current-card-id] { background-color: rgba(var(--duoUser), 1); }` block in `_card-deck.scss:644-696`. Keyed on `data-current-card-id` (present only when `current_significator` is set per `my_sign.html:20`) rather than the absence of `[data-phase="landing"]` — picker also lacks the hex but should keep --priUser. Mirrors how `.my-sea-page[data-phase="picker"]` swaps bg in `_gameboard.scss`.
(2) **Stage card + stat block centre in the aperture.** Default landing left-anchored the stage natural-sized at the top of the column (above the hex which filled the rest); w. the hex gone there's a wide empty page bottom. `.my-sign-page[data-current-card-id] .my-sign-stage` overrides to `flex: 1; justify-content: center; align-items: center; padding-left: 0;` — stage grows to fill, card+stat-block centre as a unit. `.my-sign-landing` collapses to `flex: 0 0 auto` + `position: static`; DEL is `position: absolute` so it walks up to `.my-sign-page` (already `position: relative`) + pins to the page corner. **2 traps caught mid-build** in the centring pass: (a) `.sig-stat-block`'s default `align-self: flex-end` (`_card-deck.scss:599`) overrode the parent's `align-items: center` on the cross axis, so the stat block floated to the bottom of the stage while the card sat at vertical-centre — forced `align-self: center` on this state. (b) `.my-sign-flip-btn`'s `left: calc(1.5rem + 0.4rem)` (`_card-deck.scss:747`) assumed the card sat flush against `.sig-stage`'s padded-left edge — true on the picker but wrong w. `justify-content: center`, FLIP landed at the stage's left edge w. the card centred ~3rem to the right of it. Re-derived left/bottom from the centred geometry: card's left edge in stage = `(100% - 2 * sig-card-w - 0.75rem) / 2` (the centred card+gap+stat group's left), card's bottom edge = `50% - sig-card-w * 0.8` from stage bottom (cardHeight = sig-card-w × 8/5 = × 1.6, half = × 0.8). `+ 0.4rem` on each lands FLIP just inside the card's bottom-left corner, same offset as the picker-side intent.
(3) **Stage card auto-rotates 180° on landing for saved-reversed sigs.** Server-side `data-polarity` attribute on `.my-sign-page` already reflected `significator_reversed` correctly (drives the polarity-themed color rules at `_card-deck.scss:917-1042` for levity/gravity ink) but the visual 180° rotation lives in the `stage-card--reversed` class which was only JS-applied via `_toggleOrientation()` (SPIN btn handler). On init w. a saved sig, `_populateStage(savedCardEl)` filled the card's data but didn't touch rotation — so saved-reversed sigs rendered upright on landing while the My Sign applet (template-driven, reads `request.user.significator_reversed` directly + conditionally adds `stage-card--reversed` per `_applet-my-sign.html:9`) correctly rotated them. Two surfaces disagreed → user read the applet as inverted ("non-reversed sig displays upside-down in the applet"). Actually the my_sign.html stage was the liar; the applet was right. Fixed at `my_sign.html:404-406` — after `_populateStage(savedCardEl) + stage.classList.add('sig-stage--frozen')`, if `revInput.value === '1'` (= saved reversed=True) call `_toggleOrientation()` once. That helper covers all three coordinated state mutations: `stageCard.classList.toggle('stage-card--reversed', on)` (visual 180° rotation), `statBlock.classList.toggle('is-reversed', on)` (swaps to reversal face per `_card-deck.scss:62-65`), `spinBtn.classList.toggle('is-reversed', on)` (visual indicator). Both surfaces now agree. Per user direction, a follow-up will lock my_sign.html SAVE to always write `reversed=False` (Tarot-tradition convention) — but the underlying rotation pipeline still has to work for room-side sig-select where reversed sigs are needed.
**TDD coverage**: no new tests — `test_landing_previews_saved_sig_on_stage` (updated in f609313) still passes as written (its assertions are around the frozen-stage + stat-block-visible + hex-absent contract, all of which hold under the centring + rotation patches). The reversed-sig-auto-rotate case is light-weight enough (one branch w. a well-known helper) to not need a dedicated FT; if it regresses, the existing room-side `_toggleOrientation` coverage in the gameboard FTs catches the helper itself + manual verify caught it here. Manual verify done on /billboard/my-sign/ w. `disco`'s saved Jack of Brands (reversed=False, renders upright + centred w. --duoUser bg + FLIP on card's bottom-left + DEL on page's bottom-right). 1211 IT/UT still green; one minor visual to chase before locking my_sign.html to non-reversed-only — verifying that a reversed-saved sig renders rotated on return (DB has none currently, will test after the follow-up).
