A.7.5-polish-5 DRY _stat_face.html partial + FLIP-btn SCSS unification + my_sign FLIP DOM move-into-card + universal hover-reveal + instant mid-flip vanish + sea-stage-card image-mode bg fix + multi-line comment syntax cleanup. User-spec 2026-05-25 PM bundle of 5 cleanup threads atop polish-4 (4554c71).

**(1) `_stat_face.html` partial** — extracted to `templates/core/_partials/_stat_face.html` per user 2026-05-25 PM: "Why are there so many individual instances of this feature? Couldn't we call the same DRY partial for each?". One partial covers all 4 stat-block surfaces (sig-stat-block / sea-stat-block / fan-stage-block / my-sign-applet-stat-block) — ~80 lines of duplicated markup collapse to 7 `{% include %}` sites (3 surfaces × 2 faces + applet × 1 face). Args: `face_modifier` (required: "upright"|"reversed"), `label_text` (required: "Emanation"|"Reversal"), `card` (optional TarotCard for applet's server-render path), `keywords_ul_id` (optional id attr on the keyword `<ul>` — sea_stage + fan need `id_sea_stat_upright/reversed` + `id_fan_stat_upright/reversed` for stage-card.js's `populateKeywords` surface-specific selector overrides). The `.stat-face` wrapper that the partial introduces is a no-op for the applet — applet's bespoke `.my-sign-applet-stat-block` rule doesn't `@include stat-block-shared` so `.stat-face` inherits no padding / display-none from the shared mixin.

**(2) FLIP-btn `@mixin flip-btn-base` + `%flip-btn-revealed` + `%flip-btn-mid-flip` primitives** — `_card-deck.scss` head per user 2026-05-25 PM: "unify the many disparate calculations we use for when we allow that FLIP btn to appear and where it appears". Each surface's flip-btn declaration now `@include`s the base (position absolute + zero margin + hidden default opacity 0 + 0.3s transition) and `@extend`s `%flip-btn-revealed` on its surface-specific reveal trigger + `%flip-btn-mid-flip` on its surface-specific `[data-flipping]` selector chain. ~30 lines of duplication collapsed to 6 lines of mixin/placeholder + 3 `@include` + 4 `@extend` calls.

**(3) my_sign FLIP btn moved INSIDE `.sig-stage-card`** + `.my-sign-flip-btn` + `.my-sign-applet-flip-btn` share one positioning rule (`bottom: 0.6rem; left: 0.6rem`) — was a sibling under `.my-sign-stage` positioned via stage-padding-relative `calc(1.5rem + 0.4rem)`. Polish-5 nests it INSIDE the card so positioning is naturally card-relative + the separate `.my-sign-page[data-current-card-id]` centered-mode geometric override (re-deriving offsets from the centred-row layout) is DROPPED entirely. The applet was already inside-card positioned; same `bottom: 0.6rem; left: 0.6rem` rule combines both surfaces in a single `_card-deck.scss` declaration. The applet's `_billboard.scss` flip-btn rule is now just a shim `@include` + `@extend` (the positioning got DRY'd up to the shared rule).

**(4) Hover-reveal everywhere** + instant mid-flip vanish — user-spec 2026-05-25 PM: "The .btn-reveal behavior here should now (1) disappear much earlier, so no independent ease-in/-out logic needed on clicking FLIP; (2) calculate its position more dynamically; be mirrored in the gameboard's My Sign applet. In all places does the hover-to-reveal-FLIP-.btn-reveal effect abate while the card is finishing a FLIP". my_sign main flipped from `display: none → display: inline-flex` (frozen-gated) to opacity-based hover-reveal on `.sig-stage-card:hover` (still gated by `.sig-stage--frozen`). Applet flipped from always-visible to opacity-based hover-reveal on `.my-sign-applet-card:hover`. Fan kept its existing hover-reveal. Mid-flip-hide changed from `opacity: 0 + pointer-events: none` (faded out over the 0.3s transition, which competed w. the click) to `display: none` — INSTANT vanish, no ease-out animation. All 3 surfaces consolidated into one combined `[data-flipping] -> flip-btn` selector list extending `%flip-btn-mid-flip`. The `:has(.flip-btn:hover)` self-pin clause (already present on fan) added to my_sign + applet too — keeps the btn visible while the cursor is on it, otherwise the btn (z-index 25, on top of the card) steals `:hover` from the card the moment the cursor moves onto it + retracts the reveal mid-click.

**(5) `.sea-stage--levity .sea-stage-card` image-mode bg fix** — user-reported 2026-05-25 PM: "the card preview stage in my_sea.html still sports the old card bg (the --secUser here) behind the card img (with the --quiUser box-shadow border)". Same source-order collision pattern as the sea-sig-card fix in polish-4: `.sea-stage--levity .sea-stage-card`'s `@include stage-card-polarity($invert-frame: true)` sets `background: rgba(var(--secUser), 1) + border-color: rgba(var(--priUser), 1)` at specificity 0,2,0 — matches the shared `.sig-stage-card.sig-stage-card--image` comma-list rule's specificity but source-loses to it (levity rule lives at line 2150, comma-list at line 705). Fix: add a `&.sig-stage-card--image { background: transparent; border: 0; }` nested override (0,3,0 specificity) — re-states the transparency under the levity polarity branch so image-mode drawn cards (Minchiate today) don't show a beige card-shape behind the PNG art. The gravity branch was already fine (its mixin call doesn't pass `$invert-frame`).

**(6) Multi-line `{# #}` comment syntax cleanup** — user-spotted 2026-05-25 PM after my polish-5 partial extraction caused visible comment text to leak into rendered HTML on 4 templates (per [[feedback-django-multiline-comments]] / [[feedback-django-comments-single-line-only]] traps the user has flagged before). All multi-line block comments I added in this polish converted to `{% comment %}...{% endcomment %}` form — covers the `_stat_face.html` partial header + 4 template include sites (my_sign.html × 2 blocks, _applet-my-sign.html, _sea_stage.html, game_kit.html).

Tests: 1314/1314 IT+UT total green (72s). No new tests — existing chip-presence + image-mode ITs from polish-4 still pass through the partial extraction. Visual verify 2026-05-25 PM via Claudezilla: my_sign main page (Queen of Coins) renders cleanly via partial w. card+stat-block; applet renders cleanly w. server-filled chip + title; carousel + sea_stage modal work via JS-populated partial includes; my_sign FLIP btn moved into card + hover-reveals + vanishes instantly on FLIP click; sea-stage-card no longer shows --secUser bg behind image-mode PNG art under levity. DRY partial extraction was held out of polish-4 as user-requested separate concern: "hold it for a separate commit, but fold the FLIP btn unification into it as the styling cleanup part" — done.

**Follow-up parked for next sprint**: user-flagged 2026-05-25 PM "If it's interfering to have bespoke rules, just allow the FLIP btn everywhere, including in my_sea.html". This needs (a) dropping the `not card.deck_variant.is_polarized` server-render gate in the applet template, (b) adding a FLIP btn + back-img element to the `_sea_stage.html` modal scaffold, (c) wiring a JS handler in sea.js (currently has no FLIP behavior for drawn-card stage). Out of scope for the polish-5 commit since it's template + JS scope; will pick up as polish-6 or a fresh sprint.
